Crash Error on Startup

Hello there

As I’m trying to run the Unreal Editor for the first time, I encounter an error and the editor closes.
(The error message is attached to this post in .jpg format)
I’ll be quite grateful if you spend the time to solve the problem.

Thanks in advance!

Hi Farzad,

Are you opening the Editor from the Launcher?

If so, could you try navigating directly to the .exe and opening it to see if it still crashes? Let me know your results.

Your filepath may differ:

C:\Program Files\Unreal Engine\4.9\Engine\Binaries\Win64\UE4Editor.exe

Hi TJ,

Thank you for your response.
No, I’m trying to run UE4Editor.exe from my windows explorer.
It crashes on 45% each time; if this information helps.


Sorry for the delay. Could you provide your crash logs and dmp file?

Also, please post your Dxdiag (system specs).

Branch : Binary
Build Version : 4.9.0
System Specs : Windows 10 x64 , Intel Xeon CPU , 32 GB RAM , Geforce GTX Titan Graphics Card

Unfortunately I can’t find any “Logs” folder in Engine\Saved location.

Are you using a beta driver for the Titan card? Make sure that you are using the latest one but not the beta driver if it is available.

If that isn’t the issue, I would try reinstalling the engine just to make sure something didn’t get corrupted during install.

Thank you again TJ for your time.

It’s actually less than two weeks I’v installed the latest driver for both my GTX TITAN and GTX TITAN Black cards. (358.50)
So I don’t think this would be something related to video card driver.


Have you tried re-installation yet?

Yes, I tried to install the engine for a couple of times, even on a second system. But each time the same problem arises for both; at the same percentage when loading the editor.

Can you try installing an older version of the editor (4.7.6 or 4.8.3) and see if one of those versions will open for you?

Thank you so much for your help TJ :slight_smile:

I have no idea how, but the problem’s resolved :wink:
