sofmisf 10 Posted July 24, 2010 (edited) Hey guys, I'm having issues installing beta patch 72197. It is the 1st beta patch I am installing. My Combined operations is all up to date but I get the error 'Arma2OA is not installed on this system or is corrupt'. The game runs fine though. I have it on a seperate SSD drive and have tried putting the .exe on that drive but still get the message. Any ideas? Also I have tried this solution and it worked for main OA.152 and it worked but is not with the beta patch. I have the Sprocket version also. FIX / WORKAROUND for the beta failing to install on STEAM build: use registry editor add registry key into HKEY_LOCAL_MACHINE\SOFTWARE\Bohemia Interactive Studio\ArmA 2 create new String value name it "MAIN" (w/o "") Anyone else having this issue?

MJK-Ranger 0 Posted July 24, 2010 The problem could be the "MAIN" in your registry. The "MAIN" is the install path of your ArmA2/OA, make sure the MAIN have a correct install path. Share this post Link to post Share on other sites
sofmisf 10 Posted July 25, 2010 Thx, My issue is I had renamed exe for crossfire. Anyone know if I can change beta exe for crossfire? Share this post Link to post Share on other sites
