I did this over a dozen different times with the same result.
I'm running the steam version of the game, I think I have the 1.1 patch, but I don't see anything in-game that indicates it for sure. I can bring up the console. I tried installing the manual patch to be sure, but it is the king of all retarded patches from the misfit island of retarded patches. That is to say, it spends 20+ minutes browsing the directory structure of C:\ and declaring that it can't find the game. No surprise, since its not installed on C:\. And there is no option to point it to the right directory.
