Can i install Arama on 2 different drives

[Dudester 0]

Can i install Arama, on 2 different drives, and on the same computer. A newbie wants to play on the same computer as me, but under a different cd key and name. He wants to install to a computer drive that does'nt have windows on. I just don't want him to have my cd key, or anything to do with my Windows Os. I say this because he has fecked up my windows so many times now. He said he will buy the game so thats not a problem.

BTW: He's my mate this is not over the internet.
