Well, I'm not exactly sure what the difficulty seems to be. I did the following: 1. Made a fresh wine 2. Installed vcrun2005sp1 via winetricks 3. Installed the .msi file included on the CD 4. Installed Fallout However, when I went to run the game, I got the same error I've been getting, that says vcrun2005sp1 isn't installed (from previous posts). Anyone know anything to try? The only thing I can think of that I haven't installed (that I had from my previous wine) is DirectX9, Mono 2.0 and/or .Net 2.0. Could any of these be the problem?
