Ok so I bought arma 2 from direct 2 drive and downloaded in about an hour. Everything seemed fine when I went to install and everything. Right at the end of install it says directx failed to install which im guessing was just because i have the latest version and it couldnt update and install. I didnt think anything of that until i tried to run arma 2 and it says the version of this software is not compatible with your version of windows and it says to check whether i need 64 or 32 bit versions. I am running 64 bit but there are no different downloads for 32 or 64 bit so I dont know what to do.
