When trying to launch the game via the launcher (with admin mode on) a dialog box appears saying: "BattlEye service installation failed, would you like to run the game without BattlEye?" y/n boxes below.

I think this might be something to do with Windows 10, however I am unsure. Before this error occurred I was joining a King of the hill server, when the game froze and I had to close it with task manager.

I have since put exceptions in firewall and antivirus for BattlEye, Arma 3 and steam in general and have run all in admin mode when testing.
