Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

4.7.4 engine crash on startup

Hello, I just upgraded from 4.7.3 to 4.7.4 and the engine will not run. It worked fine before the update, but since installing, nothing works. It crashes after loading up to 45%, no matter if I'm opening a fresh project, or trying to load an existing one. The bug report window offers no insight. It gives me my machineID, and my EpicAccountID, and then says "no minidump found for this crash."

I have rebooted, I have verified successfully, and finally, I have removed all versions of ue4 and reinstalled it. Nothing works, and it is consistently crashing at the same point. If you have any ideas, it would be appreciated. Thank you.

EDIT: I have included a dxdiag. I am seeing some feedback regarding UE4 at the bottom of it. Perhaps something to do with UE4Editor_ShaderCore.dll? Though I admit, I'm not the best at parsing this info. Thanks again for any help. link text

Hi cpenny20,

This sounds like an issue that we are aware of and it's been logged as JIRA UE-13250 in our tracking software.

To help us track it down, could you post your MachineID and EpicAccountID from the crash report? As long as you submitted the reports, we should be able to track them down.

Any Log and Dmp files from the crash could help us as well. Here is info on how to find those files.

Also, your dxdiag link goes to a 403 Error for us. Try just attaching it directly to your post.

Hi cpenny20,

The latest hotfix (4.7.5) is now out. Please give it a try when you get a chance and let us know if it fixes this issue for you or not.

Hi TJ, thanks for your reply. Unfortunately even after updating to 4.7.5, the issue remains. It is still crashing at 45%. Here is my MachineID and EpicID



No minidump found for this crash.

I have tried to attach my DXDiag.txt, but I'm getting an error box that says "no such upload". In lieu of that for the moment, I'm pasting the final bit of the file that is repeated several times. This is after the crash from several days ago.

The 'No such upload' error sometimes happens on AnswerHub. If you try to re-upload it 2-3 times it will generally upload correctly. Or you can try zipping all of the files together and uploading them.

Also, don't forget to submit the crashreport. It allows us to track the crash to see if it has already been reported.
