Fiskbatch 6 Posted August 18, 2012 "ArmA 2 OA is not installed on your computer or the installation is corrupted."Is what I get for error message when I try to run the beta patch. I moved my Steam folder from the C: partion to the D: partion of my harddrive. It didn't work right away so I decided to reinstall ArmA 2.Help me forum users, you are my only hope.

Fiskbatch 6 Posted August 18, 2012 Obviously, reinstalling didn't work. I have done nothing other than to uninstall arma2/oa on steam. So no complete wipe of the dayz files etc. Share this post Link to post Share on other sites
