Actually I almost did the same thing. I play using a Arma II Launcher so I just added the launcher as a nonsteam game, and the game still works fine with the Steam overlay. Thanks for the help though :)

Unfortunately I get the same issue with the default _runA2CO.cmd file. I tried to copy/paste the default ArmA2OA.exe file as well as the _runA2CO_beta.cmd file, but it still doesn't work with Steam. I can safely play with a launcher though, so I don't know where the issue is here.

I bought the game on Steam, everything works fine if I use an external launcher to launch the game. I've been playing for a few days, but I don't have the Steam overlay, so I followed the steps, and when I try to launch Combined Operations on Steam, I get a command window for half a second, I managed to take a screenshot. Last night I somehow got into the game through Steam and when trying to connect to a server I got this message : I downloaded your pre-configured _runA2CO.cmd file, and everytime I reinstall the game ( 3 times so far ) it doesn't switch back to the old _runA2CO.cmd file. Do you have any ideas how I could make this work ? I would really like to play on Steam with the overlay, but it's been 3 times so far, I might as well just play without if it doesn't work. Thanks :)
