Unreal Engine Crashes on Launch - No error message

Hi,

So I signed up, downloaded and installed the Unreal engine yesterday and all went smoothly until I finally came to launch the engine/editor. The Unreal Editor splash/loading screen pops up for a second or two at most and then just disappears. No error message and nothing launches. I’ve looked at various fixes and problems others have been having but nothing has helped me so far.

I’m wondering whether I should install it on my C Drive as currently it is on a fairly new drive just for storage but other than that I have no explanation as I believe my PC specs are adequate.

I’ve included my dxdiag and a crash log for reference.

Thanks for any help.

error info

Is this compiled from source or downloaded from the launcher? I guess from the launcher from what I see in the log.

Could you delete the DefaultEngine.ini from the game and see if it launches? The log states that it could not patch that one (or you cancelled the patching process).

I mean the once from the project you are trying to load (/Config/DefaultEngine.ini). Instead of deleting the whole file try to reduce its content to the bare minimum.

Yes, from the launcher.

There are quite a few different DefaultEngine.ini files but I tried deleting a variety of them one at a time. Some caused the launcher to fail while others did nothing.

I tried the DefaultEngine.ini from the unreal front end folder, as well as a few template ones so I only tried one or two. I also tried the one in the UnrealEngineLauncher > Config area, which was the one that stopped the launcher from working.

Doesn’t seem to be changing anything I’m afraid, still just tries to launch the editor for a few seconds before disappearing.

And if you re-download the sample?

You could try to use a source build and so you can debug the issue.

Once you got it build from sources let us know it its working ^^.

I’m glad to help, that’s what then community is for :smiley:

No changes.

I think I’ll do just that and I’ll also be testing it on another PC later this week, though I really hope I can get it working on this one
Thanks for your time and help.

I downloaded and installed it on my other work PC which is running windows 8.1 but a bit less powerful in specs. Works fine, no issues at all which is both good and bad as I really don’t need it on this PC.

I’m going to try re-installing it on my main PC on the C drive even though it probably won’t make a difference.

Hi ,

Did re-installing the editor work for your main PC or are you still having this error?

Still having errors, I installed a few different versions as well but no luck. I know a few people have had some success after re-installing windows, but honestly I’d rather build a new PC if it’s going to come to that because backing up everything on this PC would be a nightmare.

Hi ,

Are you attempting to open a specific sample or are you attempting to open a blank project with no additional content? I looked at your dxdiag and from what I can see your computer should be able to handle the editor quite well.

Hi ,

Typically I’m just trying to open a blank project but have tried opening a variety of the sample projects with no luck. I would have also thought my hardware wasn’t the issue but I’m kind of out of ideas as the editor just disappears before ever opening. So it doesn’t even feel like a real crash if that makes sense.

Hi ,

Have you tried installing the Github version to see if the problem is with the binary version specifically?

Just so I can close out this question along with the other one I posted, my issues continued with the github version until I googled my new error which read, ‘A 64-bit debugging operation is taking longer than expected’.

Luckily someone had posted an answer to a similar problem and the solution lay in running cmd.exe and entering the following two lines.

  1. netsh winsock reset catalog

  2. netsh int ip reset reset.log hit

It says you need to restart the PC but I don’t believe it’s necessary and after that I just tried the normal launcher again and it booted up properly for the first time!

Thanks for all the help/advice.

Cheers.
