Ragingbear505 10 Posted July 30, 2010 As the title indicates I recently updated to 64 bit Windows 7 and formatted my harddrives. I've since reinstalled Arma 2 and Operation Arrowhead from Steam but when I run Combined Operations the command prompt runs but the game never launches, I can run each individually just fine, just not together.

Dwarden 1103 Posted July 30, 2010 please make sure you run STEAM as admin start both ARMA 2 and OA at least once before you run CO mode Share this post Link to post Share on other sites
