Unreal Editors not launching - 9% Initializing

Hello, I cant get unreal to start up at all. It just sits at 9% seemingly doing nothing.

I also cant launch 4.10, and the ‘verify’ button for each is grey out and cannot be clicked.

I first noticed this issue with just one project a couple of days ago, (a pretty much unaltered shooter example I was using to test out things in.)

But now after installing 4.10, I am having this issue with everything.

Please help me, this is a big issue for me as I literally cant do anything here. My internet is painfully slow as well, so just reinstalling it and downloading engines is not ideal as it will take me over a day per Version.

Thanks,
Graeme

I have now managed to verify both engines, but it had no effect. they still hang at 9%…

I have uninstalled both Engines, and removed folders from Epic Games folder - I will now just install 4.10.1 and see if I have any luck.

I will update once that is done downloading, still looking for tips and advice though.

Versions 4.10.1 has finally finished downloading again, and frustration continues.

Still stuck at 9% - how can this be?

Uninstalled again, this time including launcher. Fresh installed launcher, now downloading 4.10.1 again.

Hello,

Please post an update once your launcher and 4.10.1 install finishes and let us know if that works for you. If not, I will be glad to offer some suggestions in an attempt to get your issue resolved. Thank you.

Hi Sean, thanks for getting in touch, I really appreciate that.

I thought it was going to work this time, when it was done installing 4.10 I launched it, and it got as far as showing me my projects. I clicked on my existing 4.9 project, and made a copy to 4.10. And then installed Substance plugin. now when I try to launch, it is getting stuck at 9% again.

Is there anyway of removing substance plugin now that I have installed it?

It could of course be coincidence however.

There is a post that details how to remove plugins outside of editor that you can have a look at: Disable plugins outside of editor? - Plugins - Epic Developer Community Forums
Let me know if advice given in that post helps you out. Following steps in that post should allow you to disable plugin without having to go into editor.

Ah, I just found remove button in dropdown next to launch. Still stopping at 9% though.

Give this a try, go to this file path: C:\Users\YourUserName\AppData\Local\UnrealEngine\4.10 and delete Saved, Intermediate, and DerivedDataCache folders. Then attempt to reinstall engine. Deleting files located in installation directory unfortunately does not remove all of files relating to that engine version, so removing these folders and performing a clean install should fix issue.

Okay, Thanks Sean.

I will give that a go! And update here asap.

Thanks again!

■■■■, no luck. It finished installing again last night, and like last time, first launch went well, and i was able to open it up like normal. This time I went straight to making a blank 4.10 project, and it opened up fine. I closed it all down thinking issue was resolved. But then this morning I went to check it (making this second launch again) and it is stuck at 9%, and this time I haven’t touched any plugins or anything. What should I do next?

  • So issue seems to be you can open up a project initially, but second time you try to open a project it freezes at 9%?
  • Could you provide your dxdiag?
  • How long are you letting project sit before ending process? Is it possible that it is just taking an unusually long amount of time to open?

Thank you

It doesn’t look like you have latest drivers from what I can see in your DxDiag. Go ahead and update those to latest and give it another shot.

Hi Sean,

Yes, from what I can gather that is issue.

and sure - (dxdiag should be attached here)link text

And I have left it like that for hours and it has done nothing.

Thanks again, this is a major roadblock for me and I appreciate your help so far.

I have installed latest Nvidia driver now, and also used Ccleaner to fix all registry issues. Are there any other drivers you would recommend updating?

It is recommended that you keep both your graphics card drivers and OS updated at all times. Since you have updated, go ahead and give it another try and see if you can get past 9%.

Everything updated, but it still stops at 9%. I’m going to try a fresh install again, but this time only install 4.9, see if my luck improves.

Could you attempt to open another project and get Logs from project’s saved folder and then upload those here? I’d like to see if we can figure out exactly what is causing it to freeze at 9%. Thank you
