I've got the Steam version of Combined Ops.

Try that one. You see the latest versions in the versions -tab and can update there if needed.

The picture means, that you havent updated the required beta version for Operation Arrowhead.

Fixed it with the following:

1. ???
   
   
2. Navigate to
   ~\Steam\steamapps\common\arma 2 operation arrowhead\
   
   
3. Rename ArmA2OA.exe or move it to a backup folder.
   
   
4. Locate the beta ArmA2OA.exe in the
   \Expansion\beta
   folder, copy and paste it to the main folder where the original exe was.
   
   
5. Open your Steam library, right click on ARMA 2: Operation Arrowhead, and click Properties.
   
   
6. Click Launch Options and add "
   -beta=Expansion\beta;Expansion\beta\Expansion
   " without the quotes
   
   
7. Add any additional launch options you want such as
   -nosplash -mod=@dayz
   
   
8. Launch ARMA 2: OA as normal from Steam and enjoy.
