I've tried installing SWAT 4 on my Windows 7 x64 PC, but when I try to play the screen goes black and eventually crashes back to the desktop talking about some unknown error. I've done a search and others claim it plays fine on their Win 7 x64 machines. Does anyone have this installed and running on their machine? I've tried all kinds of compatibility modes. I have an x4 955, 4 GB RAM, and 8800 GTS 512. It was running fine when I had Vista x86.
