I bought ARMA 2: Combined Operations on steam a couple days ago, so on steam I've got ARMA 2, ARMA 2: OA and ARMA 2: OA Beta. I have run all of these multiple times. I have tried using the play with six launcher as well as the dayz commander launcher and both give me the same issue.

Whatever server I choose, it always runs the game and then when the game is loaded shows the following:

I have tried removing the file and that just causes more errors when the game tries to start - and I don't know how to install additional keys.

Running on my laptop which is-

AMD Phenom II P960 X4 1.8GHz

4GB RAM

ATI Mobility Radeon HD 4250 256mb

Windows 7 HP 64b

Your registry isn't being written correctly...

1 you NEED to run steam as administrator(right click on steam .exe/compatibility/check run steam as administrator/ click apply), then run both games individually all the way to the menu, to rewrite your registry.

2(if this donst work, go to games library in steam, right click on the .exe for ARMA2 go to properties/local files/ click on verify integrity of game cache, then repeat for OA, then repeat step 1

if this still fails.... you will need to delete your registry keys. then repeat the process... but get back to me if thats the case
