So whenever i try to start up ArmA 2 OA, it gets the the "Bohemia Interactive" screen, then it shuts down and i get an error message saying "Bad serial number given in setup" :mad: .
This does not happen for ArmA II.
I just used the game to play DayZ btw, had been playing that for about a week before i got this error.
I get when i try to launch DayZ and when i try to launch ArmA II OA.
I have read dozen's of threads about people have the same problem as me.
I have read about numerous so called "fixes" but none of them worked for me, so if anyone knows of any other ways to fix this problem, please tell me?
Fixes tried:
Re-install both ArmA II and ArmA II OA
Verify game cache
Run everything as Administrator
Run ArmA II BEFORE launching ArmA II OA
Go into Regedit and delete the Bohemia Interactive + Bohemia Interactive Studio folders (wouldn't let me delete the ArmA II OA folders)
Try to copy the ArmA II "KEY" Binary code in regedit and paste it into the ArmA II OA folder (wouldn't let me do that)
