This is an experimental build error...
I download the most current experimental build (0.53) then try to launch the game but nothing happens. I get the little icon to show that my PC is trying to do something but nothing opens up.
I then try to launch the .exe file directly from the DayZ folders but have an error message stating that MSVCP120.dll is missing from my system.
I have tried verifying game files with no avail.
I can launch and play the current stable build (0.52) with no problems at all.
