This is new installer for OA's BE, so in case someone has problems - try run it, it's blazing fast install so most people not notice progress (so fast it quits) (check software uninstall list, it's under "BattlEye for OA uninstall")
If BE is same or newer it does nothing, if BE is older it updates it, it will install it if no BE found:
