Right click on Start > Search. Type rundll32.exe in the field for files to be searched for. Choose to search your primary drive (usually C). Enable Search Hidden Files and Folder from Advanced Features. Click on Search button to begin the search. In the list of results, locate the rundll32 file associated with C:\WINDOWS\ServicePackFiles\i386. Right click on rundll32 to the left of the aformentioned directory and choose "Open folder location". The rundll32.exe file should be hightlighted when the folder opens. Right click on the file and choose copy. Next, in the search results list, right click on rundll32 that corresponds to C\Windows\system32\rundll32.exe and choose "Open folder location". Again the file should be highlighted. Right click on the file and choose delete. Right click again in a free space within the folder and choose paste. If this does not solve your problem you may need to get a windows os disk and extract the file from there. Sometimes deciding which battle to fight

C:\Windows\rundll32.exe should not exist - rundll32.exe should be in c:\windows\system32. If you are getting the message when the computer boots, use e.g. Autoruns to locate and disable the autostart entry for the item referencing c:\windows\rundll32.exe. Consider scanning your computer for malware with e.g. MalwareBytes AntiMalware.

You probably do not need to reinstall rundll32.exe. However, since you didn't give any indication of why you think you need to do this I can't give you specific help. Are you getting an error message at Startup? Or can't you run any programs because you get an error involving this file? If the latter: 1. Run Doug Knox's .exe fix from here: http://www.dougknox.com/xp/file_assoc.htm 2. Then thoroughly scan your computer for malware because it is infected. Do not skip the preparatory steps. http://www.elephantboycomputers.com/page2.html# Removing_Malware If you need more help, post back with the results of those two troubleshooting steps and more details about your computer and any error messages.

Rundll32 is simply a program that runs a .dll file that is fed to it.  You don't have much to go on. Try examining the System and Application Event Logs and see if any errors are recorded there: Start -> Run -> "eventvwr.msc" HTH, JW

Let me translate the solution of Full System Restore for you: "I have no idea what is going on with your computer or how to fix it, so try this and maybe it will work." The c:\windows\system32\rundll32.exe file is one of 3498 Windows Protected Files. so it is unlikely to be missing.  That means that if your Windows File Protection is working, it is almost impossible for that file (or any of the 3497 others) to really be missing.  The file is more likely to be infected or has been replaced by some version of a file with the same name from malicious software. You could just replace rundll32.exe it with one of the many other good copies already on your HDD and that may relieve your symptom, but not fix the problem - your computer would still be infected. I would not recommend trying to work around the problem, I would recommend fixing the problem (not fix the symptom of the problem). Is your system functional enough to get on the Internet or not?  If yes, do this: Perform some scans for m

When you said you were seeing the option to browse the files on the cd I immediately knew you were not booting from the disc. This option does not appear when you boot from the disc. It only displays when you insert the disc after windows is loaded. When booting from the disc, place the disc in the disc drive then restart the computer. A screen should then appear instructing you to press any key to boot from a cd. At that point, press any key. Follow the prompts from there. If you are not receiving the screen to press any key then it is likely the boot sequence in system bios is not set properly. It should be set to boot from the cd rom first and the hdd second. However, rundll32 errors do not occur for no reason. It is my experience the most common cause is an infection. I recommend you ask this question on the free computer support forum below where you will be guided through a series of procedures to determine if in fact you are infected.

Other Memory Hogs You probably have many useless programs starting automatically. You can disable these programs. Click Start - All Programs - Accessories - Run and type msconfig Then go to the Startup tab. Untick things you don't need. Use the command line column to find info on the file, if it's not showing use View menu - Select Columns. Use the containing folder name and also find the file and right click - Properties - Details tab to see what it is.

This may not be helpful, but when my computer started giving message missing rundll32.exe, it turned out to be a loose connection to the modem.    Of course, in the meantime, i did a system restore before I discovered that !

Hello TimMcVey, 1. Does this happen when you try to open the files on the Internet Explorer? 2. Did you make any changes to the security setting on the computer before having this issue? 3. What is the security software installed on your computer? If you have this issue with Internet Explorer, I suggest that you reset the Internet Explorer settings and check if you have the same issue. Reset Internet Explorer settings. To use the Reset Internet Explorer Settings feature from Control Panel, follow these steps: a. Exit all programs, including Internet Explorer (if it is running). b. Click Start, type the following command in the Start Search box, and then press ENTER: inetcpl.cpl The Internet Options dialog box appears. c. Click the Advanced tab. d. Under Reset Internet Explorer settings, click Reset. Then click Reset again. e. When Internet Explorer finishes resetting the settings, click Close in the Reset Internet Explorer Settings dialog box. f. Start Internet Explorer again. Disclaim

Hello, Tim Having multiple anti-virus programs installed will usually cause a conflict which can cause problems. As such, I would first recommend choosing what AV software you want installed, then uninstall the other. After uninstalling the second AV software, check if the problem persists or not. What virus did you have before? Try resetting IE as suggested by Irfan.

I don't use internet explorer, and when I tried to reset the settings the same box as before has popped up blocking the Windows Host Process (rundll32.exe). As far as I know I haven't changed any settings and the UAC isn't letting me do anything, even some of the administrator options are being blocked. I have Kaspersky Internet Security 2011 and Microsoft Security Essentials installed for my security. I did have some viruses that were messing with Internet Explorer could that be the cause?

hi Tim, I'm also having this problem now... it started with my widgets not working And then, i can't even change my system's timing and date which makes it date back to 2009 (Lenovo laptop resets timing when laptop battery drains) and I have certificate expiring problems... Have you had your problem solve? I wouldn't want to go through the process of re-imaging my laptop. Troublesome :(

Lynette, if i were you I would start a brand new topic/question since this one did not have a happy ending and trying to follow it will result only in agony...

These answers address Vista; I have Windows XP.  Is there a solution for Windows XP?

this problem is for windows xp not vista

Check out Sysinternals' Autoruns , and try to find instances of rundll32.exe.  Uncheck the offending one. If you can't identify it, consider posting the rundll32.exe entries you find, and maybe someone can provide some guidance on which would be appropriate entries to disable.

I use a single Internet Suite (Kaspersky) but several standalone malware scanners, run regularly but not always loaded on startup. I tried a Vista repair using the install DVD to no avail. As the sole user of this computer, I am logged in as Administrator (even in the cmd window title bar this is indicated) so I don't know why I can't view the logfile after running sfc. I will try your suggestions regarding "how to get to the log", then try the other suggestions. I have to work in Safe Mode, though, in order to get anything done - would this affect Administrator privileges? I thought maybe if I copied the c: partition to an unallocated part of a second hard drive, replaced the "corrupt" rundll32 with a good copy, set the new c: partition as boot partition with the original hard drive disconnected, and boot from it. I can easily recover data from the first HD later (provided this method works...)

You can't do a system repair/upgrade from Safe Mode - you have to be in Normal Mode.  Safe mode affects many things you can do on the  PC - not from priviledges but because certain programs and services are not available. Rahter than doing what you suggested (which would just be moving the problem to another drive), I'd do a clean install of Vista onto the second HDD http://support.microsoft.com/kb/918884 .  Then set it up as a dual boot scenario: http://windows.microsoft.com/en-us/windows-vista/Set-up-a-dual-boot-system-from-Windows-Vista-Inside-Out .  Boot to the new drive and then copy over your data from the old drive.  Then remove the old drive, put the new drive in it's place, and reboot.  That should change it to C: drive (if it doesn't, you can do so in Start / Control Panel / Administrative tools/ Computer management / Disk Management and right clicking on the partition with your OS).  This should also break the dual boot scenario, but if it doesn't use the procedures to set i

Thanks for your replies. I think the clean install is the way I'll go... too bad though - the computer was set up so nicely. I really can't think why the rundll32 got messed up... any ideas for future reference? David

I have no idea.  It probably just got corrupted (that can happen to any file but it happened to one that's particularly important).  All you can do to prevent that sort of thing is simple maintenance.  Here are some suggestions: http://windows.microsoft.com/en-US/windows-vista/Optimize-Windows-Vista-for-better-performance . Good luck to you! Lorien - One - MCSE/MCSA/Network+/A+

You say you use "regular AV apps" - plural.  Do you have more than one AV program installed and running at the same time?  If so, uninstall all but ONE.  You can only have ONE AV application installed and running at the same time or you cause conflicts, freezes, and all sorts of problems).  That alone could be the cause of your problem (though I doubt it). You've already tried all the standard first steps to troubleshooting this problem. Do you have a genuine Windows Vista Installation Disk (or can you borrow one from ANYONE)?  That would be the quickest solution to your problem - a system repair/upgrade.  But to do that we need the disk. I don't understnd why you can't open the SFC log.  Are you getting a permissions error even logged in as an administrator?  That might tell us a lot about what's wrong.  Here's an article on how to interpret that log and how to get to the log (if you can get to it): http://support.microsoft.com/kb/928228 .  It shouldn't be guarded by permissions, espe

Hi, If you need to check for malware here are my recommendations - these will allow you to do a thorough check and removal without ending up with a load of spyware programs running resident which can cause as many issues as the malware and maybe harder to detect as the cause. Hope this helps. Rob Brown - MS MVP - Windows Desktop Experience : Bicycle - Mark Twain said it right.

Hi, Be sure to check with the System Maker's Support (motherboard maker for custom systems), their on-line documentation and drivers, and their forums (if any) for known issues. Maybe these will help. (If you think there maybe malware see the next message.) References to Vista also apply to Windows 7. Hope this helps. Rob Brown - MS MVP - Windows Desktop Experience : Bicycle - Mark Twain said it right.

Your computer is still severely infected. Back up your data and do a clean install/factory restore of Windows. http://michaelstevenstech.com/cleanxpinstall.html - Clean Install How-To http://www.elephantboycomputers.com/page2.html#Reinstalling_Windows - What you will need on-hand MS-MVP - Elephant Boy Computers - Don't Panic!

I would say that it is a virus trying to reboot. Often, some viruses (usually the more well made) will have .dll files that help that virus control your computer, as these viruses are often more intricate than other low level types. And, as a fun fact just for you, these virus .dll's usually have funky names that don't apply to anything. I could be wrong, but I just searched for "makatizi.dll" on my computer with no hits. If a virus scan won't work in eradicating the little bugger, you have to erase your hard drive and start over. If you want to do this, remember to have your Windows XP disk handy, along with any other disks you need for your favorite programs. Good luck!

Hi Edward, It could be that an application is blocking you from changing some settings in Windows. As a first troubleshooting step, we suggest that you boot in to Safe Mode and attempt to change some settings in Windows from there. Booting in Safe Mode would start Windows in a basic state, using a limited set of files and drivers. If you are able to change some settings in Safe Mode , it would mean that the default settings of Windows are not causing the issue. This way we would know if the problem is caused by a third-party application or by Windows itself. You may start your PC in Safe Mode in Windows 10 by following the steps on this link . We look forward to an update from you.

graph spikes when rundll32.exe is used Rundll32 runs something else.   You would need to find out what that something else is to understand (and then perhaps work around) your symptom.   See if you can get Task Manager's Details tab's Command Line column to show you more?   If you haven't used TM that way yet you will have to add Command Line to the list of columns being shown. Good luck Robert Aldwinckle ---

I've tried this also. I know it's a corrupted rundll32.exe file. I know under another question one of the guys sent a link to this file from his own personal computer, but that expired. (side note: when I open up task manager the top bar is not there.)

Scratch that LemP. I went back through the steps and found I missed one. Everything worked, and now the only issue is that the top bar (status bar) of the taskmanger is still not showing up. I think this is a setting that got misconstrewed, but cannot remember where/how to fix this.

...ain't buttin' in but just a copy/paste: It sounds like you are running Task Manager in tiny/small footprint mode. If you double click the empty space around the border of the Task Manager display it will switch back to regular mode and then you should see the tabs you are used to seeing. You can read about it here: http://www.broadbandreports.com/faq/6905

Thank you for your response. In case you have further question, please reply to this post for me to be notified and get back to you. Regards.

Hi Conrad, Rundll32.exe is a program used to run program code in DLL files which is part of Windows components. There are viruses that uses this name also that's why it's commonly mistaken as a real virus. There are also times that  the file gets replaced with a malware infected one. I suggest that you use the System File Checker tool to scan your system files and to repair missing or corrupted system files. The sfc / scannow command (System File Check) scans the integrity of all protected operating system files and replaces incorrect, corrupted, changed or damaged versions with the correct versions possible. You may refer to this link for more information. I will wait for your response. Regards.

Hi Aisa, Thank you for contacting Microsoft community and we will be glad to assist you with your concern. This issue could be due to missing files or any third party application is causing the issue. It would be great if you could answers these questions in order to assist you further.

If you need any other information about Windows, feel free to post your questions and we will be glad to help.

Hi, That could be cabling, hard drive, or motherboard issue affecting the hard drive. Likely to be related to the BlueScreens.

Thanks, Rob.  I suspected as much.  Toshiba support has instructed me to do a full wipe and reinstall of everything to rule out any software issues before they'll investigate hardware issues.  I guess that will be my next step, but it sure isn't sounding good.  It's still under warranty thank goodness.

Hi MANSOORALI 75, When do you receive the error message? Have you made any recent changes on the computer? Do you have any security software installed on the computer? Refer the article below and check if it helps. Cannot find the Rundll32.exe file when you open Control Panel http://support.microsoft.com/kb/812340

Hi, Method 1: Follow the steps provided below to reinstall ‘rundll.exe’. a) Put the Windows XP CD ROM disk in the CD ROM drive. b) Click on ‘Start’ , and then click ‘Run’ . c) Type expand ‘X:\i386\rundll32.ex_ c:\windows\system32\rundll32.exe’ in the Open box, where ‘X’ is the letter of your CD ROM Drive. d) Restart the computer. Method 2: Perform SFC scan and check if that helps. The SFC /scannow command scans all protected system files and replaces incorrect versions with correct Microsoft versions. F ollow the article given below to run SFC scan. ‘Description of Windows XP and Windows Server 2003 System File Checker (Sfc.exe)’ http://support.microsoft.com/kb/310747

Dear:  : Before you suggest expanding a file from an XP CD or running sfc /scannow, you need to find out if the user has a genuine bootable XP installation CD that has the same Service Pack as their installed Service Pack (most people don't). If they do not, sfc /scannow is going to complain - alot, so why do you suggest it?  Why don't you just say "I have no idea what the problem is or how to fix it". Running sfc /scannow will not replace the missing rundll32.exe file. Why do you continuously  post "Methods" that do not work and will only waste time? Why don't you post some directions on how to replace the file when the user has no genuine bootable XP installation CD and that will be useful to everyone, or at least post some ideas that actually work (that means you have tried them yourself). If you do not know how, say "I do not know how" and I will help you.

I wasn't sure which file to download so I saved "3498 sfc files" to my download directory but didn't see it there.  When I tried to download it again it told me that the file was already there so I assume it's hidden.  However, it seems that since my rundll32.exe file is missing I have also lost my ability to "unhid" files and, as an aside, to remove software from my system using the Control Panel utility. So, I have three questions: 1.  Did I download the right file, 2.  Can you suggest how I might read the file, if it is the right file, 3.  If it isn't the right file, which file should I download and how to I read it if it is hidden? Thank you, Rich

Nope. That is just a text file of the 3498 files that Windows File Protection and the System File Checker care about. Roll down the page a bit and look for the file: rundll32 Depending on your browser, you may not see the .exe extension on the files but download it anyway and save it to someplace you can remember...  like your desktop. Then look at the file and if it does not have the .exe extension on it (rundll32.exe) rename it and add the .ext extension. Then copy/paste the file into these folders: c:\windows\system32 c:\windows\system32\dllcache    (that is where XP keeps backup copies of important files). See how that works out for you.

Just a quick note to say "Thank you" for the files. They have really come in handy. Thanks!

I do not know how

Hello Sharon, The Rundll32.exe is used to launch functionality stored in shared Dynamic-link library files or DLL . This is a valid part of Windows, and normally shouldn’t be a threat. To ensure that there's no missing or corrupted files from your computer, we suggest running a System File Checker tool. For more information, click here . Let us know how it goes. Regards.

Dear Ernie San, I appreciate your information and advice on this Pestercating .dll32 problem that has developed on my little Dell. A few things I've found out is that I have a 64 bit system, but some of the movie sites I go to have 32 bit viewing / sound enhancements. Seems like dll's appear with NetFlix, PubFilm and Cucirca.uk.  I'm pretty sure these dll's have to do with the Sound System. Just ordered a new set of speakers, which I needed any way. I've also found out my Excede (ViaSat) Satellite company has just limited my monthly "Band Width" use unless I want to pay an additional amount per MB or GB of use.  (I've got a call into these people, because there service/speed has never been worth a darn and now they want more money for it. First installed in Winter and the installer aimed the Sat at a bare tree.  Spring came, leaves grew and my service went very sketchy.) I'm certainly going to try the System File Checker, later this evening, and I Thank You for your help.  I'll let you

May 18, 2011 Hi...   I am using AVG 2011 Full Version and it caught 'something' and went ahead and quarantined it.   However, now I have all kinds of problems, especially with being able to open programs from Desktop shortcuts, being able to do anything in CONTROL PANEL.   Seems that the file extension ".EXE" is no longer associated with "Application" and as a result, anything with .exe after it doesn't know how to run...!!    I am a pretty clever, savvy geek and managed to suss-out the heart of the problem...   But the ral problem, cause, what-have-you, is that the RUNDLL32.exe file is missing/corrupt.    I have tried several things to fix it, but to no avail.   I need an XP SP3 rundll32.exe file and specific, step-by-step instructions on how to get it installed again. Good help appreciated! Thanks, Cal

Hi, 1) Did you make any changes on the computer prior to this issue? Let’s follow these methods & check if the issue persists. Method 1: I would suggest you to run an online virus scan : Microsoft Safety Scanner http://www.microsoft.com/security/scanner/en-us/default.aspx Note: Any data files that are infected may only be cleaned by deleting the file entirely, which means there is a potential for data loss. Method 2: For Control Panel issue, you may follow this link & check if the issue persists. Cannot find the Rundll32.exe file when you open Control Panel http://support.microsoft.com/kb/812340 Method 3: You may also run System File Checker [SFC] scan on the computer which will replace the missing or corrupt files & check if the issue persists. http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/system_file_checker.mspx?mfr=true Hope this helps!

Many thanks for your advice. I actually found the answer on another thread before I got to try your suggestions. This is what worked: "To resolve this issue, follow these steps: 1. Put the Windows XP CD ROM disk in the CD ROM drive. 2. Click Start , and then click Run . 3. Type expand X :\i386\rundll32.ex_ c:\windows\system32\rundll32.exe in the Open box, where X is the letter of your CD ROM Drive. 4. Restart the computer 5. Press Start and select Run 6. Type CMD and press Enter 7. Type regsvr32 rundll32.exe and press Enter" Happy days! N

It could have also been an file image execution hijack, where a regkey was made that stated when rundll32.exe is launched, run a different program. And because that different program wasnt present it was telling you that it cant find it. Viruses often do this. -Alex

Hi mrleahy2648, Welcome to Microsoft Windows Vista Community site. I would suggest you to Check for errors in Event Viewer. This usually happens when a Microsoft DLL dependency is missing, and the application does not start on the destination computer. You can also try using the Event Viewer to find more information regarding this issue. You can check the log around the time the crash occurred, or you can recreate the crash for current information and revert back with more details. Also let me know when this error pops-up. Here's an article on Event Viewer: http://support.microsoft.com/kb/947321 http://windows.microsoft.com/en-us/windows-vista/What-information-appears-in-event-logs-Event-Viewer For more information, visit the following Microsoft Web sites: è Side-by-side assemblies: http://msdn2.microsoft.com/en-us/library/aa376307.aspx è Why C runtimes are installed to the WinSxS folder: http://blogs.msdn.com/martynl/archive/2005/10/13/480880.aspx Let me know if that does or does not

well i know that Rundll32.exe is a legitimate Windows file (its just as far as i know there should be just one in PC, Win8 is new to me), but what concerned me was there more then one in my PC, are all of them legitimate? or does windows creates a new Rundll32 file for a program that needs it when that program is installed?

Hello Sugram, Thank you for posting your question on Microsoft community forum. I really appreciate your concern. Rundll32.exe is a legitimate Windows file which executes .dll (Dynamic Link Library) modules which are used to store common pieces of application logic that can be accessed from multiple applications. Since there’s no way to directly launch a DLL file, the rundll32.exe application is simply used to launch functionality stored in shared .dll files. You may also refer this article: Rundll32 http://technet.microsoft.com/en-us/library/ee649171.aspx I hope this information helps. Please do let us know if you need any further assistance. Thank you

Hello Sugram, Thank you for your response. Yes, Windows creates an associated "Rundll32" file with a program. However, sometimes, these files may be detected as an infection like a spyware. I would suggest you to run Microsoft safety scanner to check for any infections like viruses or malwares. Refer: Microsoft safety scanner http://www.microsoft.com/security/scanner/en-us/default.aspx Note: Any data files that are infected may only be cleaned by deleting the file entirely, which means there is a potential for data loss. I hope it helps. Thank you

Got It but its first time i hear about Microsoft safety scanner, i have Avast antivirus, malwarebytes & spybot & this 3 have not found any infections yet, spybot only found junk, threat level green, so just junk so it works like this, awry Microsoft safety scanner download has 10 day's then u download new when u need it & it has also 10days? if so i  guess it has no install, its just kind a program that u just copy i also have 26 csrss.exe running, no idea is it normal, is it normal for some systems & PC'S?, but my question is, dose Microsoft safety scanner find the source of that to if its not infection?

Hello Sugram, Thank you for the reply. If you need more information about "csrss.exe", please refer to suggestions from Kosh Vorlon - MS MVP replied on February 24, 2012. http://answers.microsoft.com/en-us/protect/forum/mse-protect_scanning/is-csrssexe-a-safe-process/26bba20c-2691-4d42-bec4-637436c53c4f Microsoft safety scanner only shows files which are infected.

Hi Damonkashu, Let us run the sfc and virus scan and check if it repairs the file. If that does not work follow the next methods listed. Method 1. Use the System File Checker tool (SFC.exe) to determine which file is causing the issue, and then replace the file. To do this, follow these steps: 1. Open an elevated command prompt. To do this, click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator. If you are prompted for an administrator password or for a confirmation, type the password, or click Allow. 2. Type the following command, and then press ENTER: sfc /scannow The sfc /scannow command scans all protected system files and replaces incorrect versions with correct Microsoft versions. More Information about SFC scan can be found in this document: http://support.microsoft.com/kb/929833 Method 2. I would also recommend you to run online Virus Scan to remove any infections, if present. Follow the link below to run the free onl

You can probably ignore the message from SFC. The answer is that the file is not malware. What is your installed antivirus program (you selected MSE when you posted) and what is your operating system version? -steve

The whole message is "Window cannot open this file:  File:   rundll32.exe" I am running Windows XP, SP3 Yes, this happens with any .exe file I try to open. My antivirus software is StopZilla and it is current until April of 2012. and also MaxPC. I have Windows Firewall active.

rundll32.exe is not an "installer."  If you are getting a message about a corrupt installer, there's something else going on.  Please provide the complete text of the error message without paraphrasing. Does the problem happen when you try to run any exe? It would be helpful if you also described the version of Windows you have, including service pack (right-click My Computer and select Properties if you don't know). Also what is the full name of your current antivirus app, and when does its current subscription expire?  What other security applications (firewall, antimalware scanners, etc.) are installed?

Yes, this happens with any .exe file I try to open. Go to http://www.dougknox.com/xp/file_assoc.htm , read the explanatory information at the top of the page, then download both the EXE File Association Fix and the LNK (Shortcut) File Association Fix and follow the instructions.

I'm glad that this fixed things for you. Malware is often the cause of the sort of file association damage you had, so you might consider downloading, installing, updating, and running a full scan with each of these free scanners.  You can uninstall them afterwards (if you don't uninstall, I suggest going into the settings for SAS and turning off the option for it to start when Windows starts).

I followed you instructions to the tee. No change. The "rundll32" file u sent me is not an executable file. That is what I believe is missing. I installed ALL of the files in the folder you sent me also. No change.  I also could not fing a folder named "c:\windows\system32\dllcache"  Is it an invisible folder? I tried to create a folder with that name, but I was prompted that there was already a folder with that name. I just dont see it.???? Thanks for your help.

I just downloaded it myself from my SkyDrive and it gets saved on my system as rundll32.exe That's weird. When I go to that directory, the .exe files all have the same icon to the left. And you're right that in the list (under the Name column), not all files have the extensions included. Actually, all files EXCEPT .exe files DO have extensions. When I mouse-over the entry for rundll32, it does indeed say rundll32.exe . However, when I click on rundll32 and get the "File Download - Security Window", and have the opportunity to save the file type is NOT recognized as an .exe! It says: Unknown File Type, 32.5KB So unless OP renames it to rundll32.exe (which can easily be done on the fly), he's out of luck. You say that when you download it, the .exe extension is intact. But I just tried it, and it isn't. I would imagine the same thing happened to the OP. I'm not sure if it's a browser issue or a settings issue. FWIW, I am using IE7. At any rate, a number of us admire how meticulous your i

Betwixt all us guys (and gals), we'll get him squared away!

Oh... I see it now (with IE7).  I mostly use Firefox or Chrome. Hey Robert Pyle, if you are using Internet Explorer, when you choose to download the file, in the File name box, it seems to just say: rundll32 You need to change that to: rundll32.exe Then save it and put the rundll32.exe in the appropriate folders. Or, you can locate the rundll32 you already downloaded and rename it to rundll32.exe and put it in the appropriate folders.  Sorry about that! I will work on adjusting my instructions in my notes (it is just a copy/paste).  I am surprised that nobody has mentioned this before as I have sent that rundll32.exe out many times.  It seems that IE7 (at least) does not pay attention to the extension shown in SkyDrive (I tried a .dll file too - no extension). It makes IE even worse than I thought! Beck to zee drawing board, ya? This is good feedback though :) Maybe someday the MS Answers forums will catch up with the rest of the world and allow things like attachments and personal mes

What do you mean it is not an executable file? Yes - the dllcache folder is a hidden, system folder so you must configure your Windows Explorer to let you see those folders and their contents. To do that, do this: Open Explorer to the folder of interest. Click Tools Click the Folder Options, View tab Enable:  Show hidden files and folders Disable:  Hide extensions for known file types Click OK to save the settings. You can undo the Explorer adjustment when you are done (if it is your desire). I would not have downloaded all the files from my SkyDrive to your system - who knows what is out there, how long it has been out there, what versions of Windows they go with...  I know there are some Service Pack 2 and some Service Pack 3 files out there.  You may have just shot yourself in the foot! I just downloaded it myself from my SkyDrive and it gets saved on my system as rundll32.exe, so I would take a look at the file you downloaded and if it is not called: rundll32.exe Rename it until it

@Sandeep Ghatuary (Microsoft Support Engineer): Why do you suggest running sfc /scannow when it will not replace the missing file? That is not what sfc /scannow does and that is not how it works. To see for yourself, do this: Navigate to your c:\windows\system32 folder and rename or delete your rundll32.exe file. If Windows File Protection (WFP) is working, the missing file will be quickly and silently replaced from the backup copy in the dllcache folder.  That is good. Now boot your system into Safe Mode or the Recovery Console so WFP is not running and rename or delete the rundll32.exe file again so now it is really "missing".  Since WFP is not running, it will not be automatically replaced. Boot your system normally and try to use a Control Panel function like Add or Remove programs and you will see the error message. Run sfc /scnnow to completion and you will see that the rundll32.exe file is STILL missing which means sfc /scannow did not replace it. Why did sfc /scannow not replac

I'm also amazed that Microsoft employees (or maybe they're just hired consultants) continue to assume every person posting here has a Windows XP installation CD (or easy access to one) and that sfc /scannow is a useful exercise. You do seem to know your stuff. Out of curiosity, when is it appropriate to run sfc /scannow? It exists for a reason; I would like to think there ARE times one could run it and benefit from it.

I uploaded a copy of the XP Pro SP3 file you need to my SkyDrive (everybody has a SkyDrive for sharing files). You can download it and when you do, put a copy of the file in these two folders (assuming Windows is installed on your C drive): c:\windows\system32 c:\windows\system32\dllcache    (that is where XP keeps backup copies of important files). Here is the link to my SkyDrive and you can look for the file you need there: http://cid-6a7e789cab1d6f39.skydrive.live.com/redir.aspx?resid=6A7E789CAB1D6F39!311 When you see the files available for download, you may not see the file extension (.exe, .dll, .cpl, .sys, etc.), but when you download them they will have the correct extension. You need to put the downloaded files in the correct folders on your system. That may not solve all your issues, but you will at least be past that part and then we can fix any remaining issues. It could be that whatever antivirus/antimalware program you are using quarantined (effectivley deleted) the rundl

I have a problem accessing programs (most) from the desktop, when I double click an icon I get the "Open with" window.  After tinkering with the computer I found the "rundll32.exe" file was showing as a paper icon instead of the ".exe" icon.  Is there somewhere I can download an new "rundll32.exe" program and install it? If you are getting the Open with window then chances are there is nothing wrong with your rundll32. It's most likely your file associations are messed up. Click HERE . Download the zip folder. Extract the files and save them to your desktop. Right click on each file and choose merge. Confirm your choice at the prompt. This should solve the issue.

Knowing the DLL name should give you the answer, as rundll32.exe is simply a program which runs functions from a DLL. The actual commandline would  be something like "rundll32.exe d:\program\mydll.dll,RunApp" (that was an example).

I can download but when I open the problem, I continue to receive prompts and being asked which program I want to open with. When I selected the program from the list, the program does not always run.

Can't run online scan as the program is .exe program. Try safe mode too but cannot access add/ remove program.  Try to create new user account in safe mode too but cannot as the system said rundll32 error, application not found

Unfortunately, it doesn't work.  There is no registry subkey for .exe or for secfile.  Any other ideas on how to fix it please?

I tried to fix the associated files using this link " http://www.dougknox.com/xp/file_assoc.htm " but the result remains the same. There are over thirty fixes on that page! Did you specifically follow Tech-Geek's advice and use the ninth one down from the top? This one: EXE File Association Fix (Restore default association for EXE files) In addition to that, use a working PC to download to a USB flash drive both executables from this page: http://malwarebytes.gt500.org/ Once your .exe association is re-established, connect the flash drive to your ailing PC and you will hopefully be able to run the MBAM installer and then install the latest (or near-latest) definitions. And then run MBAM. Once the malware is removed, there is a good chance your ongoing rundll32.exe problem will be resolved.

Hi boatman4.  Run a scan with your antivirus program however if the symptoms persist, I suggest that you get your operating system checked.  Specialised utilities may need to be run to reveal the source of infection however the procedures are not appropriate to post here.

That's right... Windows File Protection looks after 3498 XP files (yes - there is a list on my SkyDrive ) If you rename or delete one of those protected files, WFP will want to replace it with the backup copy that it keeps in the DLLCACHE folder (that is what that folder is for).  That is why you can't simply delete it and replace it - you don't have time.  WFP will replace it for you since that is what WFP does.

[Norton] advised that the slow boot process meant that Norton performs a check for virus updates and because the IP address was not allocated in time there was no internet connection and the process timed out. (thats how I understood it). That sounds plausible I have now set the IP address "as Fixed" rather than dynamic to try to get round that eventuality That's unlikely to help. There are a number of network activities that take place when your computer is booted up.  If your network adapter is configured with the Windows default to have its IP address allocated automatically, one of the activities is a short series of messages between your computer and a DHCP server (generally in your home router).  Unless your computer has been turned off for more than a day or so, the "lease" of the computer's IP address will probably have not expired, and the computer will request that the DHCP server "reallocate" the same address.  This is a shorter process than the IP address "allocation" proce

Your error report from NIS seems quite common.  I haven't really looked at many of the posts, but I've seen suggestions to uninstall NIS and then run Norton's Power Eraser and I've also seen a suggestion to uninstall NIS 2013 and go back to NIS 2012. Frankly, if I were you, I'd uninstall NIS using the Norton Removal Tool and then install some other amtivirus product, especially if your NIS subscription is anywhere close to the end.  You can get any number of opinions on what a/v to use, but my suggestions are Microsoft Security Essentials (free) or eset NOD32 Antivirus (not free; and not the SmartSecurity suite).

Hi Hubert, These are important Windows process that runs several Windows services. Usually this can be resolved by simply installing the latest Windows updates or running a full anti-malware/antivirus scan to remove possible malicious processes. You may also try to run the System File Checker tool using the command line sfc /scannow on Command Prompt to repair damages on system file integrity. Ideally, you can use the Process Explorer tool to check what services or processes takes how much of your hardware resources. This may be a bit different to your case, but you can check this thread to see how techspeeder resolved a similar issue. Let us know if you need further assistance.

Hi Barton, There might be a corrupted system file that caused the error message on your computer. For us to isolate the issue, we will need to ask you a few questions: What task are you trying to perform when you got the error message? Any recent changes made prior to the issue? Does the same issue occur on a different user profile? What is the build and version of your Windows? You can also perform a clean boot on your device. This helps eliminate software conflicts that occur when you install a program, an update or when you run a program on your computer. You can check this link for assistance. Feel free to contact us if you have further inquiries.

Hello Nafeezul, 1. Have you made any changes on your computer prior to the issue? 2. When exactly do you receive this error message? Perform the following troubleshooting methods: Method 1: I would suggest you to place the computer in a clean boot state and then check if it helps. You can start Windows by using a minimal set of drivers and startup programs. This kind of startup is known as a "clean boot." A clean boot helps eliminate software conflicts. To set the computer in clean boot, follow the steps from the link: How to perform a clean boot Note: After checking in clean boot, follow step: 3 from the article to reset the computer to normal boot. Method 2: Perform System File Check to fix the corrupted system files and then check how it works.

It is a legitimate Windows file but sometimes it may be compromised by or a similar file may be created by malware. Why do you think the file in your computer is malware?

Now v 7, update 5 10. Firefox, Safari. Firefox used rarely, Safari never. 11. Yes - clean install July 15th after losing DISK0 in RAID1 system. Removed DISK0 and made DISK1 non-RAID and installed clean OS 12. Yes Things seem to have improved, now that Java's installed. Can't imagine how I overlooked that. [sheepish grin]

Seems strange that installing Java would improve system performance. You don't need java unless you have programs that call it or play online games that use it. My office VPN needs Java for a mainframe session via the web browser, for example. And the training courses offered online through a vendor are java based. Installing it when it isn't needed should have no effect on system performance. -steve

No, this would be normal on a 64 bit version of Windows. There is the 64 bit environment and the 32 bit. -steve

1. One of my two RAID1 disks failed - the boot disk. I could not afford a replacement, so disabled the RAID system and re-installed Vista on the 2nd disk. 2.

Probably - the registry cleaner always creates a restore point, but I don't know where. I installed the cleaner because I had lost sound on flash and wasn't able to restore it. The reg cleaner did so the first time it ran. I will try running without it, having read the aumha.net material you referenced. There is definitely something wrong, as the system remains sluggish. I recently posted another question elsewhere because file sharing is turned on every time I boot, even though I turn it off manually every time I turn the system on.

Were there any changes made on the computer prior to the issue? 2. If the issue is not resolved, please reply with more details and we will be glad to help you. Thanks.

Start with this . If it doesn't help the download the associations for exe files from this page .

here are 2 solutions: A: go to C:\Windows\winsxs search for rundll32.exe if found copy it to C:\Windows\system32 as rundll32.exe if not found follow plan B B: open system restore restore your pc to the first point you find once the system is restored go to C:\Windows\system32 and copy rundll32.exe to another drive or device then undo the restore operation then after the restore is done copy the copied rundll32.exe to C:\Windows\system32 as rundll32.exe THANK YOU VERY MUCH :)

Hello ccnaguru, 1. When do you get this error related to Run32dll.exe? 2. Since when are you facing this issue? Regards, Savan – Microsoft Support.

I did the security check & it said I had 0 viruses.  I still show on my Administer Event Viewer that I still have 45 some thousands on it.  How can I get rid of these viruses, Trojans?

TIP: If you can not access or run the CMD as administrator, you need to reboot in SAFE MODE/with networking. then you can log on as administrator.  you will probably find that everything WORKS in safe mode too. Hmmmmmm. I have the same problem.  I have my 2 copies though in windows 32 and winsis, same size, same install date. So running sfc now to see what's up. also seem to have one in Malware Bites too. No viruses detected, but doesn't mean anything, I had the Win 7 2012 virus one time and no anti virus software detected it but you knew you had something the totally took my computer over, took a long series of fixes to rid that one. Ok, ran SFC , Win still cant access c;/ files in regular mode, only safe mode. I noticed that on top of regular RUNDLL.EXE files (2ea) I also have RUNDLL.EXE.MUI. dOES ANTONE ELSE HAVE RUNDLL32.EXE.MUI, EMPHASIS ON THE.MUI part? The CBS log repot from the SFC scan said acessing the CONSENT.exe file failed referencing the KB2442962 file. ANY Thing???

It is really helpfull to me....... thnx

Hi DaveM121, Thank you very much for the support. I've downloaded the tool and run Autoruns64. You surely better know what to delete or disable. rundll32 run all the time and it is not uncommon for rundll to use over 95% of the processor, even when nothing other is running. My solution until now was to kill that processes...

Hi jyprivat, Untick those top two items marked N/A Then restart your PC and see if that CPU usage has subsided

Hi DaveM121, I have untick both and it's pretty quiet at the moment after restart. Let's hope that it will no more cause problems... Any ideas about concrete next steps please? Thank you very much and have a great day!

Hi DaveM121, yeah that's right. Thank you for that and take care!

Hi DaveM121, I hope you are doing well. rundll32 came back and stronger :( This was on a second account set on the same pc, so for that I will run Autoruns again. In my account one process appears sometime, but it cannot be find with Autoruns. Do you have any idea pls? By the way in I've killed the 3 processes in the second picture... Thx

Hi DaveM121, great, done it. I've started Autoruns64 as admin and deleted both. don't think that it's about crypto currency, may be something with Lenovo Yoga 900. This is my second ultrabook and the first one also had the same issues. I got that issues every time after changing OS from Win10 Home to Edu. May be the a weakness somewhere...

Hi jyprivat, Okay, since that fixed the issue, go back into Autoruns, making sure to start that utility as Administrator Right click those two N/a processes and choose Delete to permanently get rid of them My feeling is that it was a crypto-currency mining infection . . .

Hi jyprivat, the main thing is they are gone from your system and that the pressure on your Processor id gone . . .

Hi jyprivat, Rundll32 is simply a host process for other processes to run on top of. it is a legitimate process and should not be removed However the processes running on Rundll are another thing altogether. It is not normal for rundll to be running on your system all the time, and from your screenshot rundll is using over 60% of your processor . .. Something on your Startup is loading a process onto Rundll, you need to find that and remove it form your Startup items Task Manager and indeed Msconfig offer only limited control over Startup items . . . Click the link below to download a small free utility that does not require installation When the file downloads, unzip it. Depending on your system, run Autoruns or Autoruns64 as Administrator With that utility, you can right click and delete any startup item in Windows Look carefully through the list for any reference to rundll, then right click that ans choose disable Boot your system again and see if the issue is resolved Before you de

I use Opera and Eset Smart Security 9. There is not a popup window but Eset shows me a warning screen.(it is original, no problem) It shows the problematic program as Rundll32.exe and shows malicious servers IPs, too. for example, 94.124.122.8 80.237.133.110 108.178.52.44 There are lots of this kind of IPs and Eset's warning screen appears every 30 seconds. I can hide this window but this won't solve the problem. Rundll32.exe will continue to try to contact these servers, it will keep reducing the performance of my computer,too. I tried to stop Rundll32.exe from task manager and stopped it. Warning screens are not showing. But after restart, they will come back. If it is possible, can I delete rundll32.exe and paste the clean rundll32.exe to the same file directory? I f it is possible, where can I find the clean rundll32.exe? Regards...

As a Windows10 user, my problem is a bit different from the most common rundll32.exe virus situation. Rundll32.exe is trying to contact to lots of malicious servers and my Antivirus program prevents it. I made a virus scan but my antivirus found nothing. As I understand it, my computer is being used to spam others, so my computer is one of the computers called "zombie". How can I fix this?

Surprised that Eset cannot deal with the issue and since this is an Eset detection recommend you seek assistance from Eset. http://support.eset.com/?segment=home&locale=en_US https://forum.eset.com/ Suggest you submit a copy of the file to Virus Total for analysis. https://www.virustotal.com/ If Eset cannot eliminate the issue suggest temporarily disable Eset and scanning with the Emsisoft Emergency Kit, Kaspersky Virus Removal Tool and/or Malwarebytes Free: Emsisoft Emergency Kit: http://blog.emsisoft.com/2015/06/09/how-to-find-and-clean-malware-infections-with-emsisoft-emergency-kit/ http://support.kaspersky.com/viruses/kvrt2015#kb Malwarebytes Free https://www.malwarebytes.org/free/ You might also try running an SFC Scan and see if it will repair/replace the "suspect" file: https://support.microsoft.com/en-us/kb/929833 If necessary you can always reset your computer.  But please carefully review the following before considering this option: https://support.microsoft.com/en-us/help/1

Delete All (Deeper Cleaning Including Add-on Data Deletion) = RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 4351 That would be equivalent to RIES so you probably would have to do that elevated, e.g. enter it in an elevated cmd window.  Does that work then? BTW I have never found where people came up with these values.  E.g. notice that  4351 =  0x10FF  so if that works, it is pretty evident that the bit  0x1000  denotes  RIES  (or at least the removal of add-ons).   However, why are people requesting those 8 other bits when only some of them are (supposedly) defined? To try to understand your symptom better you could run  ProcMon  and see in detail what that the set of bits you specify  causes.   E.g. if  255  really doesn't do anything any more even when the task requesting it is elevated perhaps you need to be more selective in the set of bits you specify by choosing a value in which all the bits that are set by it are defined?

Hello Starcruiser322, The Run32 errors are mostly caused if the programs files are not loading. I suggest that you reinstall the Halo game and check if you have the same issue. You can remove it from the control panel and try to reinstall the game. You can also try to update the drivers for your display adapter and check if you have the same issue. You can check out the below article that will give you information on how to update drivers: http://windows.microsoft.com/en-us/windows7/Update-a-driver-for-hardware-that-isnt-working-properly Thanks, Irfan H, Microsoft Answers Support Engineer. Thank you thank you and thank you again. I wasn't sure if the program was at fault or trying to run a 32 bit application was. I have the latest graphics card, so no updates. I reinstalled the games (3) I was having problems with and it SEEMS to have worked.

I am having a similar problem, after some katusha packed virus, for which my kaspersky said "restart to fix" and I did, and now have this problem on mostly with my main login id (the one that counts!).  On my son's login id, foxfire and some other things work but not everything is on that id. On the main id no applications open, I am given an "open with" option like Cooler mentioned above, but these don't work right or really open anything either.  On the main id, I lost all my lower taskbar links, including the one to my kaspersky, java, etc. From what I've read its a RUNDLL.EXE problem, I tried one reinstall fix that suggested looking in a difft folder and copying it from there and pasting it in Windows, but the folder they mentioned was not there. :( I have XP. What is this "command.com" that BurrWalnut mentions, if I try first suggestion and need to try this, what is it, where do I find it? ...help...

Thank you joelj1964! It worked, keep up the great work and have a great rest of the day!

.... What is this "command.com" that BurrWalnut mentions, if I try first suggestion and need to try this, what is it, where do I find it? ...help... If you cannot follow my instructions above, it might be better if you asked someone, perhaps a friend, to help you run the two programs.

Yo Joelj1964, hi you doin'? I liked your 'to the point' instructions it grabbed my attention. Sir, I AM TECH handicapped. Also poor. I seem to create most of the computer injuries every few times I log on. Now I see on these pages I've stumbled on that my problem is common. I clicked the link as told in 1st par. exe.fix. What next? I'm not sure if anything has been corrected.

As you cannot run the Command Prompt from a shortcut, try navigating to \Windows\System32, right-click cmd.exe and choose Open. If that fails try using the program command.com. Now try the assoc .exe=exefile command again and restart the computer.
