'' ARMA 2 OA is not installed on your computer or installation is corrupted.''

Recommended Posts

Well, I installed all my game and when I was playing, he asked me to install an update (1.62). So I went on the website of ArmA 2, and downloaded the patch, but when I click install, I get the following message:'' ARMA 2 OA is not installed on your computer or installation is corrupted.''

I wonder how can I solve this! Thank you :)

That usually means the patch installer can't find the registry entry for Arma2. Do you generally run Arma2 as administrator? If so, doing the same with the patch installer should fix your issue.

If this doesn't help, you're going to need to provide some more info, such as which distribution of the game you have, how you installed it, etc.
