Magnum Johnson 0 Posted August 13, 2012 To make a long story short I am working on a friends PC and I need to install arma2 CO steam version on his PC. I have the retail copy, is there a way to install the disks using the steam CD keys and make it all work correctly? Share this post Link to post Share on other sites
