A rather complicated issue

[pieflavor 38]

I'm running Arma 2 OA beta 94876 build, on the following specs PC

- Intel i7 2630QM @ 2 GHz

- ATI radeon 6770m

- 4 GB RAM

when I launch through sixlauncher: game launches successfully, but apparently it only launches Arma 2 OA, not CO, I can play DayZ perfectly, but when playing any singleplayer arma 2 mission the screen gets stuck at a position, the map is empty (just like in DayZ) and I cannot do anything

when I launch on steam, both launching OA and CO, I get the "error creating direct3d graphic engine" which is a typical error if you're using steam withouth admin rights.

Thing is:I'm running steam on admin and sixlauncher seems to make it launch, but only for dayZ, I get the following "expansions": dayz, beta, arma2, expansion

there should be no reason not to be able to launch OA or CO through steam directly if it can be successfully launched through sixlauncher

I suspect it has something to do with a beta patch, since prior to updating to 94444 I had no problems playing the vanilla arma 2 missions on a dayz launched session.

any help would be much appreciated.

another thing: if I launch arma 2, not OA nor CO, I can play it perfectly, further increasing my suspiciousness on the beta patch.

So it still works through Steam, correct?

no it doesn't work through steam, it gives the direct3d engine error, although it works on sixlauncher but only for playing dayz

I had this once, it was because while I was downloading CO my net went off and back on in and instant (as it sometimes does) and managed to corrupt the installation.

Try reinstalling it mate :)

hmm thanks, I verified integrity of game file cache and it managed to launch the game on steam

but the problem still persists in that every single mission is unplayable except for dayz
