Unreal Launcher Error (No version information received.)

(I have uninstalled the launcher)

As a workaround, I got on Github and compiled the engine. I open Unreal Ed and click on Marketplace:

When I select ok to install I get the following error:

I was hoping this would be a workaround to install the launcher and get it working. Does anyone know how to get passed this error? I don’t want to install the Launcher through the Unreal website account page, as it’s completely broken.

Really need to get this solved; sucks to have a lecture on UE4 coming up and I can’t work on this- thanks!
