One day, my Norton just stopped opening with an error - <path>uistub.exe unspecified error

The error reads as follows:

C:\Program Files (x86)\Norton Security Suite\Engine64\20.4.0.40\uistub.exe

Unspecified error

 

I saw several potential fixes in the forums but none seems to have any affect. I have cleaned with Norton removal tool and reinstalled. I tried to open Norton in the folder using uistub.exe. One problem I found was that the path is looking for uistub.exe in 20.4.0.40 folder. That folder does not exist on my PC. The folder that contains uistub.exe is 21.1.0.18.

 

Norton seems to be running and protecting but I cannot run update or scans manually.

Let me know if you need anything further
