That's going to be tough. A hundred people watching from around the church... Please don't spoil the event, go in or don't log in.

If that does not work, shut down steam. Run steam as admin. Start and close arma2, start and close a2:operation arrrowhead. Then play DayZ. I had "some" :@ trouble. Thank You for great guide, but I would add that line of information :)

1:exclamation:) Error: Launching a2:CO here:http://pastebin.com/eaNYvGip 2:exclamation:) Short description: Cannot launch "a2:CO". "A2" works, "A2:OA" works, "A2:CO" does not work (error above), "A2:OA -mod=@DayZ" does not work, keep getting the same error this thread is about. ...chernarus So, I should keep "A2:OA -mod=@DayZ" but launch the game "A2:CO" like instructed at dayZ installation information ? Now, this I cannot get to run. Unless I do it manually (3): 3:exclamation::-/) Long description: Cannot launch a2:CO (bought from steam)... Did try with a2 and a2:OA, those work. When using -mod=@DayZ on a2:OA I keep getting that same error this thread is all about. Only armaII or armaII a2:OA will run, not a2:co. Nor a2:OA with "-mod=@DayZ". Deleted all content, reloaded a2, played a bit (last mission), reloaded a2:OA played a bit, installed dayZ, same "CABuildingParts" and ingame error (menu:"no entry 'binconfig.bin/CfgVehicles/Citizen1.scope'" and when launching game "...deleted content.chernarus". So, I should launch a2:CO, but then I get errors and game doesn't start, I guess registry key missing. Could set those paths myself and launch "%_STEAMPATH%\steam.exe" -applaunch 33930 "-mod=%_ARMA2PATH%;EXPANSION;ca" which expands (I guess) in a .cmd file named PERKELE.cmd: cd C:\Program Files (x86)\Steam\ steam.exe -applaunch 33930 -mod=C:\Program Files (x86)\Steam\steamapps\common\arma 2 operation arrowhead;EXPANSION;ca -nosplash Now I can run a2:CO (I guess it IS that, at least it launches and shows arrowhead menus, don't know what it should show though...). So modifying that to TryFinallyDayZ: cd C:\Program Files (x86)\Steam\ steam.exe -applaunch 33930 -mod=C:\Program Files (x86)\Steam\steamapps\common\arma 2 operation arrowhead\@DayZ;EXPANSION;ca -nosplash So, I get nowhere. Sigh. So back to A2:OA, like this: C:\Program Files (x86)\Steam\steamapps\common\arma 2 operation arrowhead\ArmA2OA.exe" -mod=@DayZ -nosplash Gives error: Addon 'dayz_code' requires addon 'CABuildlingParts" when I click OK game runs. Game menu and error: "No entry bin\config.bin/CfgVehicles/Citizen1.scope" And DayZ when joining gives same error this thread is all about. ".chernarus". So who does .cmd, any help ?
