therev709 10 Posted May 15, 2011 I'm having the exact same problem, just reinstalled W7 and while Arma2 works, Arma2 OA and CO won't :( I have tried copying the A2 key in the registry and adding it to the OA folder, did not work. I've also tried running it as an admin to no avail. I'm using Steam too BTW. Share this post Link to post Share on other sites
W0lle 1047 Posted May 15, 2011 Sorry, but is it really asked too much to spend at least a few minutes with using the forum search before starting yet another thread about the same problem: [Resolved] ArmA II Steam Version - Bad serial number given in setup [solved] Bad serial number with Steam install? Solution - Verify cache / Run as Admin [Answered] "Bad serial number given in setup" NOT STEAM VERSION Bad Serial Number Given On Setup Steam gives wrong CD key given at install on A2 start Bad serial number given in setup Bad Serial Error on startup Share this post Link to post Share on other sites
therev709 10 Posted May 16, 2011 Sorry, but is it really asked too much to spend at least a few minutes with using the forum search before starting yet another thread about the same problem: I personally have searched, found those threads, but non of that has helped. Reinstalled, deleted registry, copied A2 reg key to OA key, and ran as admin as per all the solutions to those threads. So somehow my computer just decided to be special :) Share this post Link to post Share on other sites

therev709 10 Posted May 16, 2011 I tried uninstalling the game, deleting all symbolance of files on my HD, and wiped all OA files from the registry the reinstalled it, and guess what, it worked! I did this once already before, but I think I tried loading CO first while this time I just started OA to allow steam to initialize everything. Share this post Link to post Share on other sites
Dwarden 1124 Posted May 16, 2011 start STEAM via "run as administator" try run game if it fails restart computer (delayed service write up by STEAM or w/e) try again, if that fails change source server in network settings, restart steam and try again Share this post Link to post Share on other sites
Tuskusson 10 Posted May 23, 2011 (edited) Had the same problem. It was solved as Dwarsen sed, by running steam as administrator :) Edited May 23, 2011 by Tuskusson spelling error Share this post Link to post Share on other sites
