Crash error while trying to install Epic Games Launcher

Hello,

I’m trying to install Epic Games Launcher on a MacBook Air, i’ve got the latest version of the software macOS High Sierra 10.13 but when I start the application it says that: “An Unreal process has crashed: UE4-EpicGamesLauncher”.

I don’t know what’s the problem, i’ve tried to install it a few times but the result is always the same.

Thanks for the help.
