Ok well If you can see most game's don't say
Windows 7 in there requirements much
Well Vista and Windows 7 are mainly the same thing
when running programs but some don't support some Windows 7
well maybe just some features when running the program
Like the Skin will Change to basic
Or
It won't run at all
Well if you see vista and you are on Windows 7
It has about 75% Chance of working
some times you can run in compatblity mode
and it will solve problems
So...
Make sure you remember this!
