I had the same issue and had to concoct my own method of solving it.Step 1: Go to Start>RUNStep 2: Type "regedit" & hit enterStep 3: Right click on "HKEY_Local_Machine" select find and search for "wow6432node"Step 4: Right click on "wow6432node" select find and search for "Bohemia Interactive Studio"Step 5: Expand the "Bohemia Interactive Studio" folder and you will see "Arma 2" & "ArmA 2 OA" folders.Step 6: Right click on the "ArmA 2 OA folder and rename to whatever, put a "1" at the end. Just so its different than what is originally was.Step 7: Right click on "Bohemia Interactive Studio" folder Select New>KeyStep 8: Rename folder created to "ArmA 2 OA"Step 9: Right click on the new folder created and select New>Binary ValueStep 10: Rename the new file created to "KEY"Step 11: Download Key Changer at http:www.cng-concepts.net/files/arma2oa_keychanger.rarStep 12: Run the .exe downloaded and enter your CD key with no dashes. You can find your Steam CD key by right clicking on ArmA 2 Operation Arrowhead in the steam library>View CD keyStep 13: After you enter your CD key hit enter 2x, until it closes.(
credit for that part goes to Dragonx2x
Then battleye wouldn't initialize. So I went to the Bohemia Interactive folder in program files (x86) and deleted it (edit: deleted the Battleye folder, not the Bohemia Interactive folder).
I then went to the arma 2 OA folder, Battleye setup, and ran the battleye setup for OA.
At this point I had to reinstall OA Beta in my library on steam
I ran Operation Arrowhead (not the beta) via steam to make sure battleye initialization was complete
happy dayz, all was well.
