Does it have to be 36 or 53 installed to avoid the problem? Or, it doesn't make a difference?

It doesn't make a difference

If you delete or rename "C:\Users\yourusername\AppData\Roaming\Opera Software" and "C:\Users\yourusername\AppData\Local\Opera Software" while leaving Opera installed, does it still avoid the problem? If not, then it probably is indeed something in your Opera profile. If so, then it probably has nothing to do with your Opera profile.

I'll try this

After uninstalling Opera, did you go into Default Programs and make sure Excel has all its defaults associated with it?

Yeah, i checked some times that Excel has all its defaults associated with it

@sgunhouse I rather think something change in the registry. At the moment I'm doing some snapshot of my registry with and without Opera installed. I will let you know if i see something different in the keys

@burnout426 said in Uninstall Opera makes Microsoft Excel 2013 not working Properly:

"HKEY_LOCAL_MACHINE\SOFTWARE\Clients\StartMenuInternet\OperaStable\Capabilities\UrlAssociations"

I checked this registry and nothing change. As i said in one of my answer, I'm currently doing snapshot of the regedit table.

For testing, you could delete Opera-related keys/strings one by one while testing after each delete to see if you can narrow it down. I'd start with the StartMenuInternet ones.

HKEY_LOCAL_MACHINE\SOFTWARE\Opera Software
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Opera Software
HKEY_LOCAL_MACHINE\SOFTWARE\Clients\StartMenuInternet\OperaStable
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Clients\StartMenuInternet\OperaStable
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\Opera 54.0.2952.60
Opera Stable string in "HKEY_LOCAL_MACHINE\SOFTWARE\RegisteredApplications"
HKEY_CURRENT_USER\Software\Opera Software
Opera Stable string (if it's there) in "HKEY_CURRENT_USER\Software\RegisteredApplications"
Opera Stable key (if it's there) in "HKEY_CURRENT_USER\Software\Clients\StartMenuInternet"
HKEY_CLASSES_ROOT\OperaStable
HKEY_CURRENT_USER\Software\Classes\OperaStable
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\OperaStable

(There could be multiple keys that when deleted trigger a fix (because the deletion breaks an association), but it's worth a try.)

I'd also look at "HKEY_CLASSES_ROOT" and check the extension keys for any extension that might be handled by Excel/Office (like .xls/.doc etc.) and check their OpenWithProgram IDs or Persistent handler IDs to see if Opera (or its ID (do a search for the id)) is listed there. I'd also look for excel-related keeys in "HKEY_CLASSES_ROOT".

It will take a while to test, but i think it's worth the try. I will keep you in touch of the progress
