Hello everybody. i formatted my computer last night before i went to sleep and i wake up today installed Arma 2 and Arma 2 Operation Arrowhead and Dayz Commander and everytime i open dayz commander its saying this Before you can start killing zombies.... it doesn`t appear you have Arma2 Combined Operations installed and/ or you have not started the game manually first. Would you like to purchase Arma2 Combined Operations right now? i already have installed what is needed! this pops up when i open dayz commander and also yes i did run both games before starting dayz commander but i dont have any idea on how to hotfix this any ideas guys thanks for reading much helped.
