THEBLITZ6794 10 Posted January 24, 2013 I just installed 64bit win8 on a new hard drive. Arma 2 is on my old hard drive. Do I need to reinstall it to take advantage of the new 64 bit capabilities (16 gigs of ram namely)? Share this post Link to post Share on other sites
frequence 1 Posted January 24, 2013 You will need to Install it again on your new System...otherwise it won't work because the registry entries are missing (Gamekey, Install Dir etc) for ArmA to run. Share this post Link to post Share on other sites
