striker3800@gmail.com 0 Posted October 4, 2012 Hi guys, every time I press the "Install" button on the Arma 2 section of the "Install/Update" tab, it does it, then just before it completes, it says, "Wrong CD-Key".Please help me. I ran it on my other computer, and it's the same as this one (Spec-wise). Share this post Link to post Share on other sites
