Have you lost your .EXE file extension association in Windows Vista?



"I have problems to start all programs that has the .EXE extension!" "My programs are broken!" "What happened to my .exe file extensions?" "I cannot run Regedit or do a System Restore!" "I'm unable to launch..." "I have an EXE file problem, the EXE does not execute"

You have probably tried to open an .EXE file with something like Adobe Reader, Internet Explorer, Notepad or the like. This results in having the .EXE file extension corrupted.

Now you really have problems since most every program requires access the exe file association to work. But there is no need to panic.

If you have this problem the solution is not the same as in previous Windows versions. Below you can see what have been added to the registry after Acrobat Reader (AcroRD32.exe) has been associated with .exe files. They need to be removed but since you cannot run regedit.exe you need to use a .reg file like one of those below.

 

Solution (only compatible with Windows Vista)

Here are some registry files that should be able to fix this problem. Download one of them and save it locally. Double click on the file and when asked "Windows needs your permission to continue" "Registry Editor" it is to give permission to start regedit.exe. Click on Continue. Then the Registry Editor will warn you again and click on Yes to add or merge the content of the reg file to the registry. You need to be an administrator to apply these fixes.

Windows Vista exe fix.reg

Here is the content of the above file. Copy the three rows below to Notepad and save to a file with the file extension reg.

Windows Registry Editor Version 5.00

[-HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.exe\OpenWithList]

[-HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.exe\UserChoice]

Windows Vista exe fix2.reg

Here is the content of the above file. Copy the five rows below to Notepad and save to a file with the file extension reg.

Windows Registry Editor Version 5.00

[-HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.exe]

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.exe]

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.exe\OpenWithProgids]
"exefile"=hex(0):

If the above ones does not help here is a more thorough one.

Windows Vista exe fix3.reg

And if nothing else works you can try this one.

Windows Vista exe fix4.reg

To see the change of the icons you might need to log out or restart the computer. But the file association should work directly.

If you want to reproduce the error save the below rows using Notepad to a .reg file.

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.exe]

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.exe\OpenWithList]
"a"="AcroRd32.exe"
"MRUList"="a"

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.exe\OpenWithProgids]
"exefile"=hex(0):

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.exe\UserChoice]
"Progid"="Applications\\AcroRD32.exe"

If You Are Unable to Start a Program with an .exe File Extension in Windows XP take a look at this knowledge base article from Microsoft. In this case a virus is the cause of the problem.

When you attempt to start a program that has an .exe file extension, the program may not start, and you may receive one of the following error messages:

    • Windows cannot find FILES32.VXD. This program is needed for opening files of type "Application".
    • Path to program is not a valid Windows application

Your desktop may appear to be blank. Also, the problem occurs many times when you restart your computer. Even after an anti-virus program has indicated it has cleaned the virus, the registry entry described in the "Resolution" section of this article is still in the registry.

Another KB is also for Windows 2000.

When you try to start a program that has an .exe file name extension, you receive one of the following error messages:

  • Windows cannot find FileName.exe
  • Windows cannot find ProgramName. Make sure you typed the name correctly
  • Windows cannot find FileName.exe. This program is needed for opening files of type "ProgramName".

This problem probably can happen also in Windows 7.

    O Great One, We give thanks and praise for the knowledge thou hast granted us, that we might undue the damage done through our ignorance, which even the Wise at Microsoft could not do.

    Or, more colloquially:

    THANK YOU!!!!!!

    All I knew was I'd destroyed the proper file association for .exe, and I couldn't find anything talking about what the association should be; lots on creating new associations, restoring to default not a thing.

    thank you thank you thank you

    Ditto - you just saved me so much time. I can't believe Intuit Quickbooks Pro 2007 has such a faulty downloader program. It totally misleads you into changing your .exe file association to whatever you have highlighted. In my case Adobe Reader. Thank you so much!!!!!!! The first fix worked flawlessly.

    I'm also having trouble still... I tried all three and none worked. The last fix tried to make acrobat reader open all my .exe files? If anyone knows of a fix that can help I really would appreciate it if you could e-mail me the help.

    Dude, yes, I am one of many people whose ass you have saved. But I have to ask, not of you, but in general, why the fuck is this OS so poorly designed that opening a file with the wrong program creates a global registry change?

    But anyway, you are a saint, and hopefully I will be more careful in the future

  42. You were recommending the creation of simple programs using Notepad.

    What does one do, though, if Notepad is yet another program that Internet Explorer is trying to run?

    ReplyDelete
  43. Alyssa O. If you have another Windows account you can use that, otherwise try to create another user account and then you should be able to run Notepad.

    ReplyDelete
  44. What? This makes no sense unless you are a tech. The instructions are not clear, where is the registry editor and which fil are you talking about?

    ReplyDelete
  45. You don't need to know about the Registry Editor. Just download one of the solutions or try them all and accept the prompts.

    The Registry is where Windows saves a lot of settings and with Registry Editor these can be edited.

    Hi, how do you save to a file with the file extension reg. I'm not very computer tech and I can't figure out what this means. If it's supposed to be in the drop down box under save as file type the only option I have to save it as a .txt file. Please help. Thank you

    ReplyDelete
  50. If you don't know how to save it with .reg extension you can just use the direct downloads that are available on the post.

    When you save the file just add .reg at the end of the file name. For example name it fix.reg

    Otherwise see these links http://windows.microsoft.com/en-US/windows-vista/Show-or-hide-file-name-extensions

  56. I can't thank you enough for this. A virus wiped out my .exe extension and left me helpless, I couldn't restore or even edit the registry manually, even after attempting to change regedit to a com file(access denied on administrator). I burned fix 4 to a CD while on another computer, loaded the file on my computer, merged it with the registry and it worked beautifully. The fix allowed me to run the system restore and get my computer back. Again, thank you.

  60. Mate,

    Thank you!

    I've spent the whole day trying to solve this. F"£$! idiots at MS kept saying download this "X" .exe and run this program... hello? Didn't I tell you I can't run any .exe?

    I also tried editing directly looking at values from another laptop, but that's on Win7 so quite different.

    Not sure how it all started though. I ran AVG antivirus and Malwarebytes with nothing detected. MS antivirus (which I ran from CMD on Safe Mode) detected 21 hazardous files too but nothing related, I think, to this.

    Any thoughts on what caused this? It started when I tried to extract a .zip file.

    Regards,

    ARV
