Still, some folks (especially those who do not play DayZ) avoid it altogether. It is a solid program with negligible footprint on your PC and there is less likelihood of messing things up. Personally, I found it a whole lot easier to let DayZ Commander keep track, download and update all the necessary files. I am sure many people have patched Arma2 manually. Unless otherwise stated, the default Arma2 install directory for this guide is C:\Program Files\Bohemia Interactive\ArmA 2 This is an install guide for DaiZySingleplayer using the Boxed-DVD version of Arma2 Combined Operations (Arma2 + Arma2 Operation Arrowhead).įor the Steam version, kindly refer to Astocky’s video tutorial here :.
