Where are UE4 crash log files stored?

My complete system was frozen after opening a detail window under
“window/ details/ details 2”.
Nothing was responsible and i had to force a shutdown.
After the restart the freeze was not reproducable for me.

Is there a logfile somewhere with logs for the whole engine?

my specs:
win 8.1 pro 64bit;
Core i7 3610QM;
geforce gtx660m;
8gb ram


I suppose you can find them over here!

c:\Program Files\Unreal Engine\4.0\Engine\Programs\CrashReportClient\Saved\

Thanks for your answer!
It seems there was no report written, because there is no directory “CrashReportClient” i my installation folder. But in the future i will watch this path!

Here you can find the paths to your logs:

Many of those listed do not appear for me. %USERPROFILE%\AppData\Local\Microsoft\Windows\ does not contain WER\; and Engine\ does not contain Saved\. Is that page outdated?
