Installing 2 games onto one system

[Zero722]

My friend and I both of DoW. Occaisionally we like to have LAN parties and stuff cuz i have 4 computers at my house, or he won't be able to play at his house cuz his parents are asian/ his house is getting painted. I have my version of the game installed onto 3 of the PCs. However, I would like to install his version onto one of the PCs so we could both play online in the same house. However, i don't want to delete my installation of the game on the PC because it's the best PC in the house and I wanna be able to use it for DoW when he's not here. It's also the only PC with enough room left to hold his version too. So is there any way to have both versions on this same PC? Maybe by editting the registry to hold 2 Cd keys somehow? If i try to install, it'll just write over my version. Any help will be appreciated. Thanks. (sorry i'm so long winded)

The easiest thing to do is to follow the instructions in this thread (http://forums.relicnews.com/showthread.php?t=51566) to change the CD key from yours to his and then back again when hes gone - it only takes a few seconds to do.

Yeah, that'd be the easiest way to do it - reinstalling it isn't really necessary, all you have to do is change the CD key.
