Installation Help

so what im trying to do is...i have a copy of NBA LIVE 08 installed what i want to do is install a second fresh clean copy on my computer so that any kind of mods i download i can apply to that installed copy....how do i install two copies on my computer?

basically all you need to do is go to c:/program files/ea sports and then copy and paste a copy of the NBA Live 08 folder

both copies will share the saves portion of the game
