sheriffhd 61 Posted September 6, 2012 If you purchased the game via steam, did you at the very least run both arma 2 and arma operation arrowhead first, thats something many people forget to do. Share this post Link to post Share on other sites
moriak 35 Posted September 6, 2012 (edited) what SheriffHD says, try to run both ArmA2 and ArmA2:OA at least once.. I'll just add that you may need to start steam as administrator before that Edited September 6, 2012 by moriak Share this post Link to post Share on other sites
