I would run the Epic Games Launcher from the Icon on my Desktop as Admin. I would stay “Please Wait…” then it would go the the “Downloading…” ‘phase’. I would run up until 4% then stop completely. I let it sit for over an hour and nothing would happen. I would check the Task Manager and it would say ‘Not Responding’. I am running Windows 7.
