I'm actually using Windows 8 and I am having the same issue. I go to start OA or DayZ and a prompt appears saying: Failed to initialize BattlEye service: Windows Test-Signing Mode Not Supported EDIT: After using cmd.exe with administrator permissions and using the command bcdedit I've discovered I'm not currently using "test-signing mode" on my PC, so I'm still confused on what exactly the issue is...
