The only reason it worked on Vista is because Starforce (not Ubisoft!) released a patch to upgrade the copy protection for Vista. For Windows 7 however they didn't release a patch so the game won't work.Supported OS: Windows® 2000/XP (only)
Fixing the problem should be relatively simply for Ubisoft, as it simply requires them to release a patch to remove the copy protection altogether. Even Starforce themselves were of the opinion that developers should release such a patch a few months after release, specifically to avoid problems like this. Ubisoft however refuses to make such commitments.
