That is odd indeed… Have you completely uninstalled the launcher and re-installed (running as administrator)? If this continue to stink for you…you could download from GitHub and compile yourself.

The button will not work its driving me crazy because i cant find another way to download the engine it makes me do it through the launcher and the launcher wont install it.

Few Weeks Ago I had the same problem, Run ‘Epic Games Launcher’ as administrator.
That has solved the problem for me.

Hopefully it will solve the problem for you too.
