I have the same problem. i have tried reinstalling the game several times. i have the 505 English version 1.01.
Tried installing both the European and international versions to no avail. I found a patch from 1.01 to 1.04 and that seemed to work fine, but the larger 1.05 patch won't run. It says the same thing: "ARMA 2: Armed Assault is not installed on your computer or installation is corrupted".
i tried pretty much all the patches, all versions... No luck.
i checked in regedit (didn't want to do too much poking around in there coz I don't really know what I'm doing!) and I found the Bohemia Interactive folder under the WoW6432Node if that helps?
