Windows 7 x64 exe not runing on double click

Posted on 2011-03-04
Last Modified: 2013-11-29

I just installed a fresh Windows 7 x64 on a brand new machine. At first all was well. After installing drivers and windows updates, double clicking on .exe files stopped working. I can right-click-> run as administrator and it works.

At first I taught it might be a virus, so I scaned, and after nothing was found, I reinstalled windows after formatting all drives. Issue is still there.

Anybody have any thoughts? I assume it might be fixable using registry, but don't know how.

If it might help, when you click a file, in the toolbar (below the address bar) you get a button with the text "Open" and an icon that represents the program that the file is associated with. In case of exe, the icon is the default "unknown" file.

It sounds to me that your registry settings for associations of executable files and perhaps shortcuts may have become corrupted.  (This usually happens through the action of viruses or other malware.)  Try the fixes for .exe and .lnk from this page:

Did you by chance format the drive? Or did you just insall over the top? If you didn't format the drive then you are going to have lots of issues. Reformat and then install.

1. double-click the "abc.exe" file. It will scan the registry for all the shell extensions.

2. Select all the non-Microsoft extensions in pink by press "Ctrl" in the keyboard.

3. Click the "Disable Selected Items" on the toolbar and click Yes.

4. Restart your computer and check if the issue is resolved.

Thanks to all for the input.

@LeeTutor & @upalakshitha downloaded the .zip, extracted, tried to run the .reg, and it says that it can't merge because the type of file is in use (I assume it's because I have programs running).

@rawinnlnx9: yes, I already said this in the question.

@niaziiftikhar: what is abc.exe? Google says it's a bittorent client

It has to be a virus. If you formatted the drive then it must be in the MBR.

Try running tdsskiller to fix that problem. You can get it here.

If it finds and corrects it then get exehelper.

Nope, i scanned, totally clean. I also have Kaspersky installed.

When I say I formatted the driver I mean that I deleted all partitions and then I recreated them.

I would check the hard drive for errors. Being a fresh install, there shouldn't be any. If there are then it's probably a bad drive.

Nothing worked.
I reinstalled windows again, and made system recovery before each install.
I finally got it working. Basically don't install all updates (don't know exactly which) for x64
