Cannot launch CO - CMD window flashes

When I right click OA and select run combined operations this appears for a split second(I Managed to print it :cool: ).

I have bought Arma II Combined Operations from steam. I installed Arma II & Operation Arrowhead, run them both and then tried to run CO. I also tried to reinstall Arma with no luck.

I used the DayZ Updater which downloaded the following rar files.

dayz_anim_v0.1

dayz_code_v1.5.7

dayz_equip_v1.2.3

dayz_sfx_v1.1

dayz_v1.2.4

dayz_weapons_v1.1.1

dayz_vehicles_v0.1

I moved them to ...steam/steamapps/common/arma 2 operation arrowhead / @DayZ / Addons and extracted them.

If I try to join a game from Operation Arrowhead I get this error:

"You cannot play/edit this mission; it is dependent on* downloadable content that has been deleted.dayz_code, dayz_weapons, dayz_equip, dayz_vehicles"

Ingame Arrowhead it says I have version 1.6.

What should I do next?

I'm having the exact same problem.

Just watched the youtube video and think I found the problem. I never ran ARMA2 from steam, just ARMA2: Operation Arrowhead. Just ran ARMA2 and its doing its first time setup, I'll let you know if this works.

Yup it worked, just open both ARMA2 and close out, then ARMA2: Operation Arrowhead and close out, then you should be able to run CO
