Tomasso 10 Posted October 29, 2009 Hello, I tried to google this problem and find it on the forums, but didnt see it so I post a new thread. When launching ARMA 2 (got it on steam) I get the message: ARMA 2 Failed to start (error code 51) I get it since I installed windows 7. Reinstalled the game today but the problem remains. If any solutions available, I'd be greatful! Tomasso Share this post Link to post Share on other sites
