You can try to go to expansions on the main menu and check if it is enabled. Another thing you could do, Im not sure though as I bought it from the BI store, stick an "@" symbol in front of your acr folder so it appears as "@ACR" then right click operation arrowhead in your steam, click properties, launch options, then type in the space "-mod=@ACR;" without quotes.

The DLC is installed upon download. It will be launched with Arma2 OA and you will see the addon as part of the installed addons on the bottom of the main screen (after intro). To verify correct installation, click expansions, and you'll see ARMA2: Army of the Czech Republic checked. If it is not, enable it, and the game will restart.

I had a similar problem. Run Steam as admin then right click on OA and ArmA II, verify cache files on one, play it, verify on the other, play it. Then shut down your PC, turn it back on again, (so Steam is restarted) then it should work I think. If not verify both games, then play ArmA, then OA, then it should work. Hope this helps if you haven't already got it working!! Good luck.

ACR Lite or full modification is installed within the game so you can enable or disable its content on your expansions tab on game start menu. Some installations follow the @NAME style and you can select your modifications using the start up settings either on steam or separately. The best way is to get ACR installed automatically with its installer via www.arma2.com so you wont need to be sellecting it once ang again

My solution of this problem:

FInd folder of ACR DLC pack:

C:\Games\Steam\SteamApps\common\Arma 2 Operation Arrowhead\DLCsetup\ACR

And then run aplication datacachepreprocessor.exe

That installed the files of DLC in the game.

When u run your Arma 2 CO with mods then your start parameters should look like:
(including quotes very important) : "-mod=Path\to\Arma 2;expansion;ca;acr;@MOD1;@MOD2;@Mod3"
put just acr instead of @ACR in your paramaters line :)

that @-Symbole just means: "That is a MOD, seperate from your game" that paramaters WITHOUT @-Symbole says "That is not a foreign file, it is included in the game!!" Mods ain't included by default!

If u run your Arma 2 CO without any mods then your start parameters should look like:
(including quotes!!! very important!) : "-mod=Path\to\Arma 2;expansion;ca;acr"

!!! Important !!!
When u write without quotes, for example:
-mod=K:\My Games\Shooter Games\Arma 2;
windows will stop reading your line at "My" because of the SPACES in the text!

TRY parameters like -nosplash and -nointro ;)

BTW: To set up your start parameters via steam:
right-click the game Arma 2 Operation Arrowhead and press "Settings"
In the new window find "set start-up paramater".

NOTE:
DO NOT COPY MY PARAMATER LINE, because that "Path\to\Arma2" should be a physical path on your hard drive!!!!
For example: "-mod=C:\Games\Arma 2" ;) ;) ;)
Good luck and have fun!


if u start your game with a batch-file and want to play WITH battleye
try:
Arma2OA_BE.exe 0 0 "-mod=C:\My Games\Arma 2;expansion;ca;acr;@MOD1;@Mod2;@MoD3" -nosplash

save this file at the same place who the Arma2OA_BE.exe is! When save it in the desktop or something else the batch-file will not work! ^^ xD
