Setting up Combined Operations ?

[Frosties]

We need some help to set up combined operations...
have been searching here but none of the threads we tried was working..

either just A2 started or just OA...

My friend has ArmA2 on steam, and Operation Arrowhead on DVD.
How can we get it to run as combined operations?

Many thanks for any assistance!!
