Delgado33 10 Posted June 18, 2011 Every time I launch the original ArmA2 and it says bad serial number given. I have Windows 7 Vista and I first contacted steam but Steam support referred to this website. I also have ArmA2 OA and it works fine. Any Suggestions :confused: Share this post Link to post Share on other sites

vohk 10 Posted June 18, 2011 Make sure you're running Steam with administrator privileges, even if you're on an admin account, then verify the game cache. (Right click the .exe --> Run as Administrator) https://support.steampowered.com/kb_article.php?ref=4950-EKAM-2644 (For a non-Steam version, just run the arma2.exe as admin.)
