Hey everybody. Let me first say i know there are many, many threads about this but even though they provide solutions they just seem not to work for me and its all getting a bit well repetitive.
I bought Arma 2 OA separately today and i downloaded it twice since then.
When i try to start Arma 2 OA 9 out of the 10 boxes tick and then as soon as it reaches the 'Bohemia Interactive' logo the screen goes poof and the infamous message pops up saying Bad serial blah blah blah.
I have looked at what are supposed to be solid solutions for about 12 and a half hours now. So far i have done the;
Run steam as admin.
Regedit.
Steam compatibility.
Verify integrity or w/e.
Run Arma as admin.
Reinstall.
Arma comparability.
The worse thing is i have done this all more than one with no avail. I'm not going to lie i was really excited it up to the part when my day was ruined by this stupid error.
