Gunter Severloh 3948 Posted September 27, 2011 Delete the file air_e.pbo if you have it and run the install again. where do you find it? follow the path: C:\Program files\Bohemia Interactive\Arma 2\Expansion\Addons\air_e.pbo error told you where and what it was giving you issues.

MrWonderman92 10 Posted October 5, 2011 I tried that and the Expansion\Addons folder does not appear, If I was to uninstall Arma 2 and then try to install Arma OA would that work ? Share this post Link to post Share on other sites
Gunter Severloh 3948 Posted October 5, 2011 (edited) No. Do this: - install ARMA2 ( may say patch 1.06 didnt install correctly, doesnt matter just install 1.10 ) - install 1.10 patch --> get it here http://www.armaholic.com/page.php?id=14589 - install OA - install patch 1.59--> get it here http://www.armaholic.com/page.php?id=13729 Run your game from the Arma2OA.exe to run Combined Ops.
