Epic Games Launcher UE4 Install button non-functional

I am new to UE4, and trying to install it for the first time on my Windows 10 desktop pc. Through the Epic Games launcher I am able to navigate to the engine tab and the click library to add an engine version. After adding v4.19 the install button appears, but clicking it does nothing. The installation does not begin and no error appears. I attached debug logging from the session. Any advice on what the problem is would be greatly appreciated.link text

did you figure it out?
