Exe files not opening

[kunkel321]

Okay, another item: This is similar to the old post here:

Dopus 9.56 won't open .exe files

This page has various suggestions: filext.com/faq/broken_exe_association.php The one at the bottom of the page is probably worth trying first, though it depends what is messed up. Seems a number of things can cause this. Also, I'd recommend not us…

If I double left click (or choose Open from the context menu), then Opus appears to refresh (so it's doing something), but the Exe file does not run. This only happens in Opus, not other file explorers.

The File Type setting is still as its default (below img). Perhaps I've accidentally activated some security feature(?)

Other notes:
-I am an admin of my machine and I don't get UAC popups.
-For a while I was getting the Win 10 "Open with.." popup, but now I don't get that either.
-Changing the Exe file properties to 'Run as admin' doesn't help.
-I went ahead and set dopus.exe to 'Run as admin' too, but that didn't help.

Thoughts?

From Settings > File Types, use File > Diagnostic from the menu at the top-left, and post the result for the .exe extension.

Cool debugging tool!

Go to HKEY_CURRENT_USER\Software\Classes and delete the .exe key below there. It should not exist.

(The key should only exist under HKEY_LOCAL_MACHINE\Software\Classes\.exe, and the other one is overriding it.)

That may be enough on its own.

If not, go to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.exe and:

• Under OpenWithList, delete the a and MRUList so there are no values there at all.
• Delete the UserChoice key entirely.

Yes that worked! Thanks Leo!

Actually the first tweak didn't work, but the second one did.
