Unreal editor "crashes" on launch

Development Platform & Builds

Hi!

I finally had time to boot my PC again to start on a project in Unreal, but:

When I started the editor the splash screen showed, but when the load status was at 0% my screen blacked out.
Testing with the UT game from launcher: Screen black, intro voice plays.

alt+f4, ctrl+alt+delete, alt+tab,win+d etc: nothing worked. Left computer on, no dice. I had to turn it off using the power button.

Reinstalled PC completely with updated win 10 (home edition, 64 bit), updated drivers etc: Same problem. Moved the engine install: same problem. Launched the editor from project location, with admin rights and still same problem.

Please note that no changes to the engine where made, no files modified in any way by me. I just installed the launcher, added 4.15 engine and tried to launch it from the launcher.

The Unreal crash reporter did not show up.

The one thing that has changed in my setup since this worked is my monitor. I now use a Dell U2711(connected with display port cable).

Other HW:
Gforce gtx 670
i7-3770k
16 GB ram
Intel SSD

NB: Other games, like Overwatch works as they should.

My gut feeling is that the editor somehow sends a non compatible signal to my monitor, but really I am at a loss on what to do, all tip are welcomed!

Regards,

Display driver updated to 378.92 and engine reinstalled to 4.15.1. Same problem.

Hey ,

You mentioned that you launched the editor from the project location, do you mean that you attempted to launch the editor directly from the .exe? If not, could you please try that? It will help determine where the error is occurring.

:\Program Files (x86)\Epic Games\4.15\Engine\Binaries\Win64\UE4Editor.exe

Also, please upload a copy of your Dxdiag (system specs) and the entire log file that you are pasting the data from.

  • Windows: Go to the Start menu and type ‘dxdiag’ into the search bar. Open the file and then click ‘Save All Information’. Post that text file here.

Note: I just tested it with the 4.13.2 engine and that works without problem.

I deleted old logs and started 4.15.1 from launcher with debug mode active

Hi!

Thank you for the reply. I have tried launching the editor from 4.15\Engine\Binaries\Win64\UE4Editor.exe, with the same result. Please note that I have installed it on a non standard location at the moment (c:\unreal) as I have tried to reinstall the engine. I can reinstall to default location if you belive that will be helpful.

Can you also get the engine logs from this folder?

C:\Users\YourName\AppData\Local\UnrealEngine\4.15\Saved\Logs

Also try disabling any programs like GeForce Experience that are running in the back ground.

Installing in a non-default location ‘shouldn’t’ cause any issues but you can try uninstalling and then reinstalling in the default engine location to see if that makes a difference.

Please see the log files attached to this post.

I uninstalled GeForce experience and 3dvision ++ (see the screenshot).

Same problem as before unfortunately.

Installing Visual Studio resolved the issue for some unknown reason.
