ARMA2 Beta patch (optional)

Beta patch is not instantly BattleEye enabled after release. You may have to wait a couple of hours to be able to play with it online. To be sure, check the corresponding thread.

Beta patch is backwards compatible, so you can still play on non-beta servers.

If you have previous beta patches it's suggested to uninstall them before installing a newer version. You can also try deleting beta subdirectory inside ARMA 2 folder manually.

Having trouble with the BETA Patch? then this forum post might help.

Make a shortcut to launch with Steam Overlay (Optional)

Instructions

1. Make a new non-steam shortcut, choose Browse then browse to your operation arrowhead directory, go into expansion then go into beta. Click on ArmA2OA.exe in that folder and choose Open. The box will close so then choose Add Selected Programs button in the steam add programs box.
2. Find the shortcut you just made in your Steam library, right click and choose properties.
3. Delete the target line.
4. Rename the steam shortcut whatever you want.
5. Now edit the following text in notepad or something similar to include your paths. If you have both Arrowhead and both ArmA2 on Steam you won't need to do this assuming you have kept the default installation location for Steam and run a 64bit OS.

Code:

"C:\Program Files (x86)\Steam\steamapps\common\arma 2 operation arrowhead\Expansion\beta\arma2oa.exe"  "-beta=Expansion\beta;Expansion\beta\Expansion" "-mod=C:\Program Files (x86)\Steam\steamapps\common\arma 2;Expansion;ca;@dayz" -nosplash

Once you're done making sure that the pathways are correct you paste that into the target line in the steam options of the shortcut, all of it.

Delete the Start In line and replace it with this, edit this if you have a different installation location.

Code:

"C:\Program Files (x86)\Steam\steamapps\common\arma 2 operation arrowhead\"

Run the game from your new non-steam game shortcut.

Startup Parameters (optional)

You can find other than default launch options, like windowed mode here: http://community.bistudio.com/wiki/Arma2:_Startup_Parameters

Common errors

I get 'You cannot play/edit this mission, it is dependent on downloadable content that has been deleted.dayz_code, dayz_weapons, dayz_equip etc.'upon joining any DayZ server

You installed the mod or the shortcut incorrectly. Make sure you add "-mod=@dayz" without quotes in the launch options and DayZ mod files are installed in the proper folder. By default: "C:\Program Files (x86)\Steam\steamapps\common\arma 2 operation arrowhead\@DayZ\Addons"

I am stuck at "Waiting for server response" or "Waiting for character to create" or "Receiving Data"

Servers are simply being overloaded, wait a litte or try another server. If nothing works try below.

Launch Operation Arrowhead from steam and select the option to re-install BattlEye Anti-Cheat client. If you are using retail download the latest version form http://www.battleye.com/download.html and put it in a folder named "BattlEye" in the "Expansion" folder of your Arma2:OA main directory.

Redownload DayZ mod files and make sure you have the latest version. http://www.armafiles.info/dayz/

If nothing works try reinstalling both Arma2 and OA.

Note: Frequent connections and disconnections on a server compound this problem. Please try to be patient before switching to another server.

I get a constant "Retrying to authenticate" message

Updating Arma2 Client to the latest beta version may resolve this issue. Latest versions are available at http://www.arma2.com/beta-patch.php

I get "You can not play/edit this mission; it is dependent on downloadable content that has been deleted.cherarus" when trying to join any server

Make sure you launch the game as 'Combined Operations' and NOT 'Operation Arrowhead' when launching from STEAM.

Invisible objects, missing textures etc.

Right click ARMA 2 in STEAM - 'Properties' - 'Local Files' - 'Verify integrity of game cache'.

Try changing your ingame video settings.

I get other weird graphic artifacts ingame that block my screen

Known bug, it occurs on the barbed wire fences that players can build and should be fixed in the next patch. You can try changing your ingame video settings as a temporary fix.

How do I change my FOV (Field of View)?

See this thread: http://forums.bistudio.com/showthread.php?100235-Setting-up-your-FOV

I get 'ARMA2 stopped working' error on launch

Right click ARMA 2 in STEAM - 'Properties' - 'Local Files' - 'Verify integrity of game cache'.

Redownload and make sure you are using the latest version of DayZ mod files.

Try launching the game without DayZ mod, see if it works. If it does reinstall DayZ mod files.

Try installing the latest beta patch (see above).

I can't use Direct Chat ingame. Mic is stuttering

Known bug. You can install the latest beta patch for Arma2:OA (see above) or wait for the official fix.

I get "No entry 'bin\config.bin\CfgVehicles\'" or similar pop-up error message when launching the game or playing on a server

Ignore it. It won't affect your game.

I get 'missing CBA_Main' when joining a server

Ignore it. It won't affect your game.
