Hitman and Windows 7
I purchased the "That's hot" version of Hitman which had Hitman Contracts and Blood Money
Worked fine in Windows XP but when I changed to Windows 7 I could not get the games to play no matter what I tried.
Then on a hunch I turned of DEP processes in Windows and both games now play under Windows 7.
Not sure if anyone else has had similar issues but thought this might help?
