Hi all, thanks for taking the time to read this post I recently bought Arma 2 + OA, installed the Day Z mod, and played for a bit. I installed everything as directed, went to launch Arma 2: OA via 'combined operations', it would then come up with the cmd, and with this error c:\program files (x86)\steam\steamapps\common\arma 2 operation arrowhead>SETLOCA L ENABLEEXTENSIONS c:\program files (x86)\steam\steamapps\common\arma 2 operation arrowhead>For /F "Tokens=2* skip=2" %A In ('REG QUERY "HKLM\SOFTWARE\Wow6432Node\Bohemia Interact ive Studio\ArmA 2" /v "MAIN"') Do (set _ARMA2PATH=%B ) ERROR: The system was unable to find the specified registry key or value. c:\program files (x86)\steam\steamapps\common\arma 2 operation arrowhead>IF NOT DEFINED _ARMA2PATH (GOTO v32_path_a2 ) ELSE (GOTO v64_path_a2oa ) c:\program files (x86)\steam\steamapps\common\arma 2 operation arrowhead>For /F "Tokens=2* skip=2" %C In ('REG QUERY "HKLM\SOFTWARE\Bohemia Interactive Studio\A rmA 2" /v "MAIN"') Do (set _ARMA2PATH=%D ) etc However, when I play the game normally, everything works fine as it's supposed to. The @dayz symbol shows up on the top right corner, I can log into current 1.5.6 dayz servers, but there's just one problem... ZOMBIES DON'T APPEAR!! If there is anyone who could possibly help please post below :D EDIT: I didn't download this game from steam, but I did purchase it on steam, I then had a friend send me his game files to me. I don't know if this has anything to do with it, but I might have some game files missing or something. I'm not too sure ~Hex
