Just open the uninst.dat (any text editor) then and looks for the path. There are many of them.
I did what you suggested...I could not make sense of what I got when I opened the .dat file and was reluctant to muck up the works by messing with something I know zip about. You're right, there were many "paths".
However, after hours of searching around the 'net to find a solution, I performed inelegant one... used Revo Uninstaller to remove references of the game from the registry, deleted the games folder and saved games and installed DKS with not a peep from my PC or the game. I am happily playing DKS.
Thanks for trying to help & Happy Holidays.
