I bought arma 2 combined operations from gamersgate.it came in 2 downloads,one for arma2 and one for operation arrowhead. I installed both, and patched both. what install method do i use for dayz ? Retail ? If so, i have a problem, as my install has no OA dir. I tried to use the dayz install tool, but it tries to find the OA dir and cant.It then tries to find the arma 2 dir and does,but then nothing downloads.....
