Bad Serial number given in setup

[zatic13 0]

I recently purchased arma 2 combined operations on steam so i could play the dayz mod at first i couldnt launch arrowhead so i decided to go ahead and still try to install the mod. i perferred to do the manual install because i just dont like auto install but when i boot up the game it comes to th bohemia interactive logo then crashes and says bad serial number given in setup. Please help I want to play day z really bad.

Try verifying your files if bought through steam. run steam as administrator. Run A2OA without launching DayZ. Try again. Hope this helps.

I think you need to run ArmaII and ArmaII OA at least once before you play DayZ.

Should fix it, try and let us know.

DUH I should learn to read every post before I, umm, post. lol

You need to run Steam and the game (Arma 2 first the CO) as Admin then it will work.
