Unreal Build Tool Not Packaging: Unable to instantiate UnrealEd module for non-editor targets: Target -> *.Build.cs -> UMGEditor.Build.cs -> Sequencer.Build.cs

Vlajd · February 6, 2022, 9:16pm

Unreal is having trouble packaging my game:

I can't figure this one out on my own, maybe someone here can help me out...
(Using UE5 on a regular Windows machine, C++ project with mostly Blueprint-C++ usage)

I have tried replacing possible c++ classes that may cause this with blueprints, but with no luck.

When I try package, the pop-up information says it packaged successfully, but the selected folder is empty and the following messages appear in the console:

UATHelper: Packaging (Windows):   ERROR: Unable to instantiate module 'UnrealEd': Unable to instantiate UnrealEd module for non-editor targets.
UATHelper: Packaging (Windows):          (referenced via Target -> *.Build.cs -> UMGEditor.Build.cs -> Sequencer.Build.cs)

Any Ideas?

You may need to build out your solution in visual studio in the drop down select Editor and then open the editor and try to package again. Code 6 is something I find when a module or something critical is missing because the editor doesn’t recognize it because it’s not creating the build.cs and target.cs files automatically or in the correct directory.

Even when adding a new c++ class it puts the darn things in the wrong directory. I don’t know if this is a bug, but I always have to move things around to get them to package correctly. Code 6 can be from a boat load of reasons unfortunately usually something missing or in the wrong place.

Na, I tried both Rider (which I usually use) and VS, but both return code 6, unfortunately.

I’ve noticed something strange in the output tho:

1>Der Befehl ""C:\Program Files (x86)\Epic Games\UE_5.0EA\Engine\Build\BatchFiles\GetDotnetPath.bat"" ist entweder falsch geschrieben oder
1>konnte nicht gefunden werden.

Meaning it couldn’t find the GetDotNet bat file. Could that be a reason why it won’t build?

Same goes for rider.

I am going to try to reinstall UE5 in a new directory, because I just found someone who had a similar problem (file not getting found) and apparently he just selected a file path with no spaces in the path, maybe that’ll fix it -_-.

And if that doesn’t work, imma try to install the required components for vs2019 aswell, instead of using the ones from vs2022, which hasn’t been a problem so far but might fix it aswell, who knows.

Well that did not work unfortunately

Vlajd · February 7, 2022, 5:51pm

So, I managed to make Unreal Package the game finally. The solution was to remove “UMG” from the *.uproject file.

Unfortunately, the executable crashes at the start, so now I gotta resolve this error. I really hope it’s because of some small mistake I made in my c++ or blueprints…

Humanasset · February 8, 2022, 12:53am

Do you have the .NET framework installed? I had to go back and install that for whichever reason it didn’t install when I installed visual studio and that was an issue for me as well. I don’t recall exactly at this point I did, but I think I had to get it off the Microsoft website.

VPK_BG · August 24, 2022, 11:56am

I know its kind of late and maybe there is more to it but I noticed that UnrealBuildTool recursively creates modules in this order: PublicDependencyModuleNames, PrivateDependencyModuleNames, and then DynamicallyLoadedModuleNames.

Therefore, if your Build.cs file has “UMG” in PublicDependencyModuleNames, but “Engine” is in PrivateDependencyModuleNames the build should fail, as UMG module is dependent on Engine module.

baldsun · September 24, 2022, 1:03pm

I had the same problem. And I solved it by remove “UMGEditor” in *.uproject
hope it can be helpful.

DrKiller · May 5, 2024, 3:15am

It works for me too, let me over explain a bit:
I opened the .uproject with SublimeText (or your editor of choice) and removed the “UMGEditor” from the list of plugins…

	"Plugins": [
		{
			"Name": "ModelingToolsEditorMode",
			"Enabled": true,
			"TargetAllowList": [
				"Editor"
			]
		}
	]

I do will like to know where the error comes from O_o …what does the plug-in does and why start buggin? …I guess there is another way to solved like making sure that the plug-in is actually in the source?
