chirf 0 Posted May 15, 2012 Just bought the Arma II: CO bundle, but launching the Operation Arrowhead didn't work.It just went through the little black box with computer code and then... nothing happened.Anyone else with this problem? I already reinstalled it, still didn't help. Share this post Link to post Share on other sites
Bower 4 Posted May 15, 2012 You need to launch combined operations, not arrowhead. Share this post Link to post Share on other sites
jordnz 102 Posted May 15, 2012 Moved to 'Troubleshooting'.If you bought CO through Steam, you may need to run ArmA 2 first, before installing and/or running ArmA 2 OA (to create the right registry entries). At least this is the official fix from a while ago. Not sure if it still applies now as BiS released a Steam update that took care of some of the CO launch stuff.
