Unreal 4 will not launch

Hi all,

I’ve just installed Epic Games Launcher and Unreal on my laptop. The launcher ocastionally works but even when it loads it won’t let me actually hit the Unreal engine tab. If I try to load it from unreal it hit’s 97% and crashes. I’ve tried doing a reinstall but it hasn’t fixed my issue and unreal isn’t throwing out any errors. Last time I installed unreal was a few years ago so I appolgise if there’s something really obvious I’m missing. I can’t seem to get ANY version of UE4 running.

Anyone know what to do?
