Unreal 4.1.1 crashing (first time launch)

Hey everyone,

Just downloaded and installed Unreal Engine 4.1.1. Click the Launch button, Editor splash screen opens, quickly followed by a crash. The crash report simply says: "We apologize for the inconvenience.
Please send this crash report to help improve our software.


I have attached my dxdiag text file. Been trying to research this on my own but can’t seem to find anything helpful. Thanks!

Hi RyanW,

Sorry to hear you’re having this issue. I don’t immediately see an issue from the Dxdiag, but have you made sure that your graphics card drivers are up-to-date?

After you crash, can you also attach the latest log that is generated here?

C:\Program Files\Unreal Engine\4.0\Engine\Programs\CrashReportClient\Saved\Logs


Hi Stephen,

Thanks for replying! I have checked my drivers and everything is up-to-date. Attached is the log you requested.


Sorry here it is - had to change it from .log to .txt link text

Your attachment appears to be incomplete. it cuts off right in the middle.

You should be able to take the original file, and put it in a Zip, and upload that here.


Here ya go :slight_smile:link text

Hey again,

Just as an update - I got the latest Unreal Engine version and it still crashes, but it’s outputting a bit more information in the Crash Report. I omitted a few byte lines so it fit =)

Hi Ryan,

My apologies for the delay in response. There are two other users who experienced the exact same crash:

Crash on Launch [4.0 - 4.2] - Platform & Builds - Unreal Engine Forums
Crash on launch - Programming & Scripting - Unreal Engine Forums

The good news is that they were both able to resolve the issue. The downside is that they had to reinstall Windows for everything to work correctly. Alternately you may be able to run something like Dependency Walker to try to identify any particular files which might be causing the issue, and try to replace them.

I hope this helps.
