Hi buscas31,

I’m sorry to hear that you are experiencing this problem, and thank you for attaching the logs. To be clear, you receive this “Unreal Engine has stopped working” message after you run the “Unreal Engine” shortcut on your desktop (to UnrealEngineLauncher.exe) and the Launcher never actually manages to open, correct?

Have you tried restarting your computer, and/or uninstalling and reinstalling the application?

If neither of the above works for you, please let us know, and also please attach your system’s DXDiag report.

Thank you.

Unreal Engine" shortcut on your desktop (to UnrealEngineLauncher.exe) and the Launcher never actually manages to open, correct? > YES,

Have you tried restarting your computer, and/or uninstalling and reinstalling the application? >>> YES. Already performed a clean install of windows 7 x64 with SP1, and have the same issue. But, the log, this time, has changed and in certain line, says" “not enough free space” (wtf? i have 1 TB HDD SATA)

See the new log. This time, i attached log from launcher and directx log toolink text

no solution yet?

Nevermind, my VGA cards fail, and i put a brand new Sapphire Radeon R9 270 X Boost, and the Engine Launch ! Tks alot!

Yes I was having this problem as well. As it turns out UE4 needs graphics card to run. Since I was using nvidia I had to right click on the UE4 editor exe and force it to run with my graphics processor.
