CrashReportClent has stopped working

Hello Felvol,

Can you attach your CrashReportClient logs found here:
C:\Program Files\Unreal Engine\4.0\Engine\Programs\CrashReportClient\Saved\Logs

And attach your launcher logs as well, found here (Replace User.Name with your windows user name):


Whenever I try to run the launcher it crashes with ‘CrashReportClent has stopped working’
Any suggestions / Bug fixes? :slight_smile:

I have an SSD and a HDD, and its not liking either of them :frowning:

Operating System: Windows 7 Ultimate 64-bit (6.1, Build 7600)
Processor: AMD FX™-8320 Eight-Core Processor (8 CPUs), ~3.5GHz
Memory: 8192MB RAM
Graphics: NVIDIA GeForce GTX 650 Ti

My CrashReportClient Log doesn’t have anything in :frowning:
My Launcher Log has quite a few logs though :slight_smile:
(For some reason its not letting me attach it)




Here we go :slight_smile:


Any chance you could post C:\Users\YOUR.NAME\AppData\Local\UnrealEngineLauncher\Saved\Logs\UnrealEngineLauncher.log? Please YOUR.NAME with your login.

Hi Felvol, thanks for the logs! Could you try doing one last thing? Open up:

“C:\Program Files\Unreal Engine\Launcher\Engine\Programs\NoRedist\UnrealEngineLauncher\Config\DefaultEngine.ini”

And add the following to the very end of the file:


That should enable verbose logging to help us track it down. Once that’s done, can you try running again and sending us the very latest log again? Thanks!

By chance can you attach a .zip of the .dmp files found in that same folder? C:\Users\User.Name\AppData\Local\UnrealEngineLauncher\Saved\Logs

Here you go :slight_smile:

Here is the Zip with the [Core.Log] LogHttp=Log LogOnline=Verbose line added in :slight_smile:

Those need to be added as separate lines like this:


Any help on this ? Looks like i have the same problem here , can’t even lauch the installer … this is a bit frustrating but eh, if it’s working soon it’s worth it !

Here are the folks working on it :slight_smile:

After doing that now, this happened too

Here are more logs and dumps :slight_smile:

Hey Felvol, can you try one more thing?

Can you try to uninstall the visual studio 2013 redistributable? Here’s what it looks like in Programs and Features:

Uninstall the x64 and x86 versions, then reinstall with the download from Microsoft which you can find here:

We think it might be a problem with the redistributable.

Hi Elunil, just to confirm, do you mean the .msi installer, or the Unreal Engine Launcher?

I didn’t have any of those 2013 redistributables installed :o, But after installing them I get

Latest Logs and Dumps - link text

This was a bug in the VS2013 math libraries causing a crash on CPUs without AVX2 features (like your AMD FX 8320) in certain environments.

We have applied a workaround by disabling FMA3 in this circumstance. We will remove this workaround when the problem has been resolved at Microsoft.

The fix has been submitted to our main branch and should be available in the next release. Sorry for the inconvenience.

I have
Operating System: Windows 7 Ultimate 64-bit (6.1, Build 7600) Processor: AMD FX™-8320 Eight-Core Processor (8 CPUs), ~3.5GHz Memory: 8192MB RAM Graphics: NVIDIA GeForce GTX 460

And I’m getting the exact same problem as you actually. Getting the crashreportclient has stopped working error but in addition for me a black windowed screen would pop up and immediately exit out just before that happened.

I wanted to be helpful and contribute my own logs, but when i added those 3 lines to my DefaultEngine.ini file I got a new issue. Instead of just the CrashReportClient the UnrealEngineLauncher also stops working. And the black window that was flashing in the background now sticks around until I close the program. As far as I can tell no logs generated.

I also didn’t have the 2013 redistributable. (after typing this) I decided to try installing it and after doing so there was no change.
I’m really excited for my shiny new ue4 subscription~, hopefully someone will figure something out before my days off are used up. X3

Hi Carlos !
Yeah i meant the msi installer :confused:

Just to say also that unlike the guys above me i have

Processor: Intel(R) Core™ i7-4700MQ CPU @ 2.40GHz (8 CPUs), ~2.4GHz
Memory: 8192MB RAM
Graphic Card : Nvidia GeForce GTX 765m

So i guess my processor doesnt have AVX2 too ?

OH OH! I dunno if i will work for you guys but. I just realized that sense my last reformat I forgot to install the win7 sp1 update. I did so and now its working fine. If you see a 7600 next to your windows version in the dxdiag window then I think you might wanna consider trying to update.

Hope that works for you guys!
