After downloading Unreal Engine launcher it still says "No Engine Installed"

So I downloaded Engine through Epic Games.
download finished and installed onto my drive.
When I opened launcher and went under the “Unreal Engine” tab it says "No Engine Installed.
I doubled checked files and it seems that UE 4.7 wasn’t present.
