ARMA: CO won't start up

[dpad (DayZ) 0]

I'm having trouble with ARMA: CO.

I installed the mod correctly and when I launch ARMA: CO, a Cmd box pops up for a quick second with a bunch of writing and then closes and that's it.

Here's the writing:

"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

ive Studio\ArmA 2" /v "MAIN"') Do (set _ARMA2PATH=%B )

operable program or batch file.

No game opens, no process appears in my task manager, nothing at all.

Any solutions?

I was having the same problem. I bought CO yesterday, but since i already had Arma2 free installed i didn't want to download Arma 2 ( i have very slow internet.) 16 hours later after Operation Arrowhead is done downloading, and i install the dayZ, i kept getting missing chernarus file. Turns out you need to launch Combine Operations and now OA, but in order to Launch CO you need to run Arma 2, and OA to get the registries linked.

TLDR: You need to run Arma 2 + Operation arrowhead, to launch Combined Ops

So i guess you need Arma 2 and not the free version.

I just got it to load, here is what I did (w/Steam):

Close Steam completely.

Find the Steam.exe in your program files and run as ADMINISTRATOR.

Log in to Steam and launch ARMA 2: OA.

Exit out of that game and then load ARMA: CO.

Worked for me.
