same here game does not start up at all i dont have a firewall or a antivirus .
i reinstalled dayz 3 times in total over 2 weeks to see if dayz fixed it itself , but no
i deleted all my arma 2 games who used to screw with battle eye and still nothing works reinstallin .net workframe and directx are not the problem
checked and reinstalled everything i can think of

Never had this problem before this update . played this game more then
