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

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