ARMA 2: CO (how to combine ARMA 2 into ARMA 2:OA and use together)

[goflam]

So, I'm having the same problem as some others with the registry key. Tried many fixes, but none seem to work.
Re-Installed as ADMIN through Steam, Opened ARMA2, opened OA
Preceded to open Combined Operations, but got the instant command prompt http://imgur.com/IQsVX
Tried a lot of different things suggested (including integrity of of cached, etc.).

So far, Six Updater allows me to open Combined Operations and play the DayZ mod, but it constantly freezes for ~5 seconds. Have not yet been able to find a solution...anyone?

Oh, and both the registry keys are there...so =(

@up
1.install A2 run the game, then patch the game with arma 2 patch v1.05.
2. Instal OA in the same folder you will have arma 2Co in version 1.50-1.52 its depends from what country you have game.
3. run arma 2 co one time and then patch the game with Arma2 co/oa/reinforcements patch v1.60 (this patch will also update your arma 2 to v1.11, and baf/pmc dlc lite to newest versions).
All needed patches you can find on armaholic.
PS:
Patch v1.60 for CO/OA and Reinforcements:

Patch v1.05 for arma 2:
http://www.armaholic.com/page.php?id=8820

PS2: your Arma 2 must be first patched to v1.05, then you can instal OA and in the end patch the whole game with v.1.60

Thanx a lot ... I think I have to drop this complicated action.
My SSD has no more room for Arma2 and I wanted to install it on another normal harddrive.
But obviously makes very complicated because hence it must be a different folder than the already installed Arrowhead ...

If you have followed all of the steps suggested here and are still having a problem getting Combined Ops to work ask your self this.

"Did I install DayZ manually"

If you did and you copied the Arma2\addons files to your @dayz\addons folder you need to delete everything EXCEPT the DayZ files.

I was having a hell of a time getting it to work until I realized this. If the Arma2\Addons files are in the @DayZ\Addons folder it will run with the OA interface no matter what you try.

Once I removed every other file from the @DayZ\Addons folder except the DayZ mod files it worked with CO just fine.

hi, i want to know if i have a steam version of arma 2 and shop version of arma 2 arrowhead can i do combained operation ???

ps. sorry for my English

[Cowgirl]

I bought Arma 2 when it first came out, and have had it installed ever since. I just bought Operation Arrowhead and installed it ( for z Day:3) with Steam but the two didn't combine. I can't play them in a single game, it only lets me play Arma 2 or Arrowhead separately. What do I need to move to change to make it work?

My Arma2 is boxed retail, and my Arrowhead is a steam digital copy.

Install oa into the Arma2 directory and then launch the game using the Arma2oa.exe

Use steam mover and move your unwanted games to another drive using this software. http://www.traynier.com/software/steammover

only works on win7.

I have disc install of ARMA 2. Steam install of OA. Seperate directories

I can start it as CO via the .bat in the OA steam folder and it works fine

I have problems with mods - I would like to run the game via launchers so i can choose which mods to use, eg sixlauncher. But when i use a launcher it seems to load up as OA & not CO. I hav pointed sixlauncher to correct directories.

So i get told i can't join as i'm missing necessary ARMA 2 files.

I think i could get it to work by adding all the relevent mod info to a shortcut to the .bat file which forces CO. But really this is not a very flexible or user friendly solution ??
