ArmA2 OA is not installed ....

When installing the latest beta patch I get the "ArmA2 OA is not installed on your computer or the installation is corrupted" message. I have been playing the DAYZ mod just fine so it IS installed on my computer. I downloaded the latest beta patch 93701 and when I run the patch exe the above message pops up. I ran it both as it is and as administrator.

How did you install your ArmA? Did you buy it on Steam, install from DVD, or got it from somewhere else?

I bought"Arma Combined Operations" from Amazon and installed it from the two CDs.

Try re-installing ArmA 2. It sounds like it hasn't been installed properly, if the beta patch can't find the registry entry for it.

Just ARMA 2 or Op Arrowhead also?

[Wüstenfuchs (DayZ) 105]

Both.

Ok, I uninstalled both ARMA2 and OP Arrowhead. Then re-installed them, applied the 1.60 patch, applied the 93701 patch which went smoothly and am able to play dayz. Thanks for the advice.
