Crash on engine launch + a host of other crashes

link textAs Requested I have attached the Logs. I have a few other problems now I shall list them below:

  • Launching anything from the Unreal Launcher regardless of whether it is the engine or a demo it leads to nothing happening. (I have submitted logs for both 4.0 and 4.1 so named in the zip file!)

  • I can run 4.0 using the Editor_Cmd.exe but i get a ton of crashes for various thing such as building lighting and going into the material editor (I have included the logs for the engine in the zip also)

  • Below is my error that I got originally referring to point 1.

  • I would really appreciate a swift response as I am eager to use this product to its full capabilities!!!

Please send this crash report to help improve our software.



If I can supply any other information to get this problem sorted swiftly let me know!!

Hey DeusVox

There are a few pieces of information that would help to know. Especially your log files and dxdiag.

Please reference the How do I report a bug? post for the information that can be helpful, including your system specs and logs to provide. Once we have that information, we will be able to further investigate.


Hi DeusVox,

Actually please follow this link which will help you to provide the best information for troubleshooting this issue:

The specific information we need to get started:

  • Your operating system and hardware specs, best by providing your dxdiag file
  • The exact steps you are taking to get to the problem. For instance are you just running the Launcher, then clicking the “Launch” button, and the crash happens immediately?
  • The crash log, which should be found here: C:\Program Files\Unreal Engine\4.0\Engine\Programs\CrashReportClient\Saved\Logs


I have amended my original crash report!

Bump as i am only limited to basic functions of 4.0.2 because of this

Bump again issues are still persisting!!

Hi Deus, sorry for the delay.

You appear to be crashing while running some ShaderCompiling processes.

We just released a 4.1.1 preview update which, among some other things, addresses a couple of shader compiling issues. None of them were causing crashes to my knowledge but they were certainly overburdening systems. I’d be interested in having you give the update a try to see if, hopefully, it might fix the problem.

Information to use the 4.1.1. preview update is available here:

4.1.1 hotfix update now available - Announcements - Unreal Engine Forums

Please let us know your results.

As far as I am concerned all the same problems are the same on the 4.1.1 version! Please I really would like to resolve this and get cracking on my project !

Are your video card drivers up-to-date?

All drivers are as current up to date and not beta.

Hey DeusVox,

Are you still experiencing this crash on 4.1.2, 4.2, or 4.2.1 (whichever version you’re on, if you’ve updated since this original posting)? If you are still experiencing this crash, please reply/bump this thread and let us know what version you are on and we’ll investigate further.
