Just installed Epic Games Launcher and from UE 5.3.2
Can’t even launch it, searched in google, seems like trivial thing that enormous amount of users encounter before even start using engine, which is unfortunate…
Welcome to the Unreal Engine Community Forum. That specific error is usually related to DirectX 12 and/or GPU and it’s drivers. What type of GPU are you running in your PC?
Recently i had Nvidia 1660, but i had to remove it so i now again on my integrated from CPU(i5-7600k), but with all NVidia stuff in OS installed and still running. I thought it might be the case, so deleted all NVidia stuff i could find. Did’nt changed anything.
Installed at least Unreal Engine 4.27.2, it runs well and good.
Uninstalled all NVidia-related apps and drivers, all related files on C: drive(just in case). And installed UE 5.1.1 now.
Went better, loaded almost all Editor, but at the end failed with the different crush:
Now, third attempt - UE 5.0.3
Went furthest of all by now. Successfully loaded to the project creation/open window, but after loading newly created project it crushed the same as previous eventually, except one new thing:
I spent an hour and managed to update to that particular recommended version(everything everywhere worked fine before, all games, 3D apps, no idea why UE5 complains).
Nonetheless, it did’nt changed situation much :
Tried different versions of my drivers. Old ones which went with my PC when i bought it(2017) installs well and without issues, as a result, Unreal Engine 5.0.3 when trying to launch do not pop-up warning message anymore, which is good. But that crash at the end remains…
NVidia gone like 3 month ago, when started with Unreal just several days ago)
So never tried.
It is all frustrate because i can use UE4 now and it runs perfectly, acceptable FPS, at least for learning&practicing. But i want to learn with UE5, ‘be in same pace with world’ so to speak:)
I understand completely. There’s a few things I’d want to check next. But, before we do that have you made any other changes to the hardware or software on the computer prior to UE5 stopping working? If not, I’d proceed checking the following:
Run Unreal Engine as administrator
Disable any custom plugins or third party modules you have added(If you added any)
Also, how much ram and storage do you have on the PC currently?
Well, some guides i applied practically when was searching relatable issues to my problem:
In Windows Registry changed(and maybe added one) TdrDelay(60) and TdrDdiDelay(60).
Added some lines(something related to port 6666 change to different like 50000) in to DefaultEngine.ini at: C:\Users\usrname\AppData\Local\UnrealEngine\5.1\Config. But then iafter nothing changed i deleted added lines back to that state.
Deleted all NVidia stuff(and after that reinstalled some UE5’s like 5.3).
And i think that is basically it.
1.) Already tried to run as Admin.
2.) No plugins or stuff, i’m new to this all:)
3.) 8gb
Good deal. The next thing I’d like to look at is to ensure it’s not a DirectX 12 issue. You mentioned that you were familiar with the DefaultEngine.ini. This is a similar step. Try this: Open your Config/DefaultEngine.ini and you’ll be changing ‘DefaultGraphicsRHI’ there. Look for the line below. You’ll want to swap it from DirectX 12 (DX12) to DirectX 11 as shown below. Let me know if that resolves it or if you get a different error.
No such thing as DefaultGraphicsRHI in such file(if we talking about C:\Users\usrname\AppData\Local\UnrealEngine\5.0\Config).
And i checked all 5+ versions, all have that folders and file in it respectively, when 5.3 does not:
I tried your two lines. It crashed as well, pretty much like every time(5.0.3):
BUT!
I just for sake of hope or something copied Config folder from 5.0.3 with newly modified DefaultEngine and put that to the 5.3.2:
And OH MY GOD it successfully launched 5.3.2 Editor with blank new project in it. With upsetting notification in the corner, but hey, at least i have now access to main thing. Thanks FrostyJas.
Im new here, I was looking for a developer and tryed downloading the epic game launcher but it just sits in the bar trying to lanch bobbing up and down, i dont have the no how to fix it. I was looking for someone that might be interted in my Idea as a game. I hope when i return its sorted.
