Ill start from the beginning when i installed the game i downloaded from direct 2 drive it installed fine then said unable to install direct x, im not sure if this is a problem or not. Then when i tried to run the game it says The version of the file is not compatible with the version of windows your runing. Check to see if you need x86(32bit) or x64(64bit) version of the program and contact the publisher. So i started looking around for a fix and downloaded patch 1.02 and it wouldnt install because it said arma2 was not installed or was corrupted so i re installed arma2 and the same thing happened. Im running 64 bit vista and had no problem with the demo (why wont the full game work??) any help would be nice Thanks.
