Runs just fine on Win 7. There does seem to be some issues with XP SP2 and below so if you decide to use XP make sure you install SP3 before playing. Another thing to watch for in XP and earlier versions of Vista is the patch was compiled using a newer version of the MS VC++ 2005 runtime libraries so make sure you update them by going to
http://www.microsoft.com/downloads/d...displaylang=en and download install vcredist_x86.exe before patching. Newer versions of Vista and Win 7 already have the newer libraries so you should be fine if you have them.
