"a setifece error has occurred"??

Some help please? I’m trying to uninstall the program but every time I do it says: A setiface error has occurred: 2. Try to reinstall or contact support, yada yada…

I reinstalled it and the same error comes up. What do I do?

If you search the board for ‘setiface’ (not setifece), will it help?

If you run C:\WINDOWS\system32\rundll32.exe “C:\Program Files\Alwil Software\Avast4\Setup\setiface.dll”,RunSetup
What do you get?

You could also download the avast! Uninstall Utility, find it here which you can use after a failed add remove uninstall.
