Arma 2 combined ops

[GeraltTheMemer]

if i download arma II and arma II operation arrowhead seperate, will they go together to make combined ops? Because i had previously bought operation arrowhead, but realized i wanted combined ops. when i bought combined ops, i chose to just install arma II, not operation arrowhead and arma II, will that mess it up or will they still combine and make one game?

Also, i was not sure where to post this discussion, sorry if it doesn't belong here.

To run ARMA 2 Combined Operations (+ any mods you like) when purchased through STEAM

1. Download/install "ARMA 2" via Steam, start the game and play bootcamp for a minute or two then quit game.

2. Download/install "ARMA 2 Operation Arrowhead" via Steam, start the game and play bootcamp for a minute or two then quit game.

3. Exit Steam.

4. Navigate to the Arma 2 Operation Arrowhead folder on your computer eg.
C:\Program Files (x86)\Steam\SteamApps\common\Arma 2 Operation Arrowhead

5. Find the file called "_runA2CO" (Windows Command Script).

6. Right click "_runA2CO" and send to desktop as a shortcut.

7. Go to your desktop and right click the new "_runA2CO" shortcut you just made and select EDIT from the right click menu.

8. Look towards the end of the document for the "runs" line - this is the line we will edit (it appears just before ENDLOCAL).

9. Mine looks like this:
(my mods are CBA, I44 and COWarmod with -nosplash at the end):

--------------------------------------------------------------------------------------------------------------------------------------

:runs
"%_STEAMPATH%\steam.exe" -applaunch 33930 "-mod=%_ARMA2PATH%;EXPANSION;ca;@CBA_CO;@I44;@COWarModI44;" -nosplash

--------------------------------------------------------------------------------------------------------------------------------------

10. Once you have modified the runs line to your requirements, click SAVE and use the shortcut to launch Arma 2 as COMBINED OPERATIONS!!!

PS. Your mods can be placed in to the same folder as the Arma 2 Operation Arrowhead exe

In my case I have copied the following modfolders in to the same folder as ARMA2OA.exe
@I44
@CBA_CO
@COWarModI44

Hope this helps somebody - took me a while to figure it out!
