Unreal Engine won't start

,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.

Specs are:
Geforce 760
12 GB RAM
Windows 7 x64
Intel i7-4770k @ 3.50GHz

I’ve reinstalled and rebooted several times.
Please help?

Unplugged all my usb devices and still no go.
Any ideas?

Hi ronaldk,

If you have Windows Task Manager running at the same time, do you see UE4Editor-Cmd.exe appear in the list after you try to launch?

black window appears and goes away. In Task manager/ Processes, CrashReportClient.exe appears for a second and it goes away immediately .

Hi ronaldk,

Can you post your log? It’s in “C:\Users\YOUR_USER\appdata\local\UnrealEngineLauncher\saved\logs”. Do you have Win7 sp1 installed?

Carlos

I should…

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.

My goodness… ■■■■ Service Pack 1–!
I did a fresh system install for this and it’s a tiny detail that totally slipped! Thank you so much, Scizz!
