theycallmeh3x 10 Posted July 22, 2013 Hey guys, I'm in a pickle. I have managed to get the Bad serial number given in setup error when I launch Arma 2 OA. It does not occur in Arma 2 however. I have tried all of the fixes I believe. I have reinstalled both arma 2 and OA, I gone and done the registry fixes, I have emailed bi studio and they basically pointed me here, I have also even purchased Combined ops on a brand new steam account and I still have this error. Please give me some guidance! Edit: I have also now tried reinstalling steam. then, redownloaded arma 2 and OA, then I made the registry changes, and tried to launch. Same error.
