Help installing ArmA II: Operation Arrowhead?

[eaglehawkaves 0]

I got the retail version of ArmA II, installed it, works fine. Now, I also got the retail version of Operation Arrowhead, and I got all these files in the map of it... I run the AutoRun application, and there IS an install button, but I cannot click on it. I can only click on some www.arma.com/ link and manual. I don't know how to go futher, any help?

EDIT: To help you understand the problem a bit, as I got no replies, I run the Operation Arrowhead AutoRun. And I have Play, View Redme and Install buttons, www.arma2.com/arrowhead and manual. Now, Play, View Redme and Install buttons are greyed out and unclickable! Here, check it out for yourself.

Is ARMA 2 patched to the latest version? not sure if that makes a difference, maybe try reinstalling ARMA 2 again then OA.

Perhaps this would help. Has Arma 2:OA install.

I see what you mean. I have you tried the right-click setup & run as admin? Are you getting this problem when the autorun pop's up? (if you disabled autorun)

Hold on guys, just tried reinstalling ArmA 2 using the setup, and it showed me the message: Uninstall Arma II: Operation Arrowhead? Could it be that by installing ArmA 2 with it's setup, I also installed OA?

Nevermind guys, I downloaded DayZCommander, and it said I don't have ArmA2 Combined Operations. Even after reinstall of ArmA2, problem is still here...
