,When I launch Unreal Engine a small black box (application) appears for a second on screen then closes. Nothing else happens. I tried running UnrealEngineLauncher.exe and CrashReportClient.exe and neither seem to do anything.

I had this issue before. I recently did a fresh install of Windows with a bad RAM stick and it caused my windows files to be corrupted. Also, from what I understand in order to run UE4 you need Windows SP1, which I couldn’t install because updates would always give me corrupted files errors or I would BSOD. So basically, make sure you have SP1, and also make sure your RAM is good.
