Have you started Arma2 combined operation once? This is required on steam versions of the game.

If you need any more help, don't hesitate to PM me.

I bought the arma 2 combined operations and steam installed it as two seperate games, arma 2 and arma 2 operation arrowhead. Ive tried running them both at the same time cus i heard that works but arma arrowhead doesnt open.

[andret 13]

did you try choosing the "Combined Operation" option on operation arrowhead?

close steam

start steam in admin (right click and run as administrator)

right click on arma2 and properties then local files

click on verify integrity of game cache <-- do it twice

and do the same for arma2 oa

run arma2 to the menu

run arma2 oa to the menu

click in expansions

make sure the following are enabled

arma2

arma2 oa

arma2 baf lite

arma2 pmc lite

if not enable them and restart then exit the game
