On Launch, URE4.7.2 displays tray icon and initializes to 100% - but does not run/open

Hi devonc01,

Could you try bypassing the Launcher and opening the ‘UE4Editor.exe’ directly? I will help us narrow down the issue.

Navigate to this folder (your file path may vary slightly):

C:\Program Files\Unreal Engine\4.7\Engine\Binaries\Win64

Open the ‘UE4Editor.exe’.
