It was discussed once before, but seems there’s no easy fix to it. I purchased SGP licence and in trying to insert it I’m getting the following message: “Padding is invalid and cannot be removed”. Tried uninstall, scanned leftovers with deletion of some (not all, some could not be removed) registry entries, none helps.
I had this problem before when I tried to extend my trial. Thought that purchasing full licence will help, it did not.
Any thoughts are appreciated.
