Hey Sea Demon.
I got Window 7 a few days before it was release,

and you shouldn't have any problems with running these games on Window 7, don't forget W7 is basically Vista refited, but Microsoft would never tell you that.
All I would say is install the game outside the Program Files folder i.e.
Something like C:\My Games\Sonalysts Combat Simulations\
any problems let us know.
