Troubleshooting Issues with Unreal Engine 5.3: Unable to Create C++ Projects or Build

Development Programming & Scripting

I recently downloaded Unreal Engine 5.3 from the Epic Launcher, but I encountered an issue where I cannot create a C++ project or build anything with version 5.3.

I have attempted several troubleshooting steps, including:

  1. Reinstalling Unreal Engine 5.3.
  2. Verifying the engine installation.

I have also made sure to install the necessary Visual Studio components, which are:

  • Visual Studio 2022 (version 17.7)
  • Windows SDK 10.0.18362 and Windows SDK 10.0.20348.0
  • LLVM Clang 14.0.1
  • .NET 4.6.2 Targeting Pack and SDK
  • .NET 6.0

It’s important to note that I can create projects using Blueprint, and I have successfully used other versions of the engine, such as 5.0, 5.1.1, and 5.2.1 without any issues.

If anyone has encountered a similar problem with Unreal Engine 5.3 and has found a solution, I would greatly appreciate any guidance or assistance.

Do you have in your Build.cs this modules?

0

the following is not necessary (You can delete it)

#if WITH_EDITOR
	.....
#endif
3 
	public MyProject2(ReadOnlyTargetRules Target) : base(Target)
	{
		PCHUsage = PCHUsageMode.UseExplicitOrSharedPCHs;
	
		PublicDependencyModuleNames.AddRange(new string[] { "Core", "CoreUObject", "Engine", "InputCore" });

		PrivateDependencyModuleNames.AddRange(new string[] {  });
	}

I have not made any changes to the default options, and upon checking, I can confirm that there is no UnrealEd

Yes, UnrealEd is not in the default configuation. it is fine…

I have not Clang installed… i don’t know what it is…

i have this things:

1

i’m installed the 5.3 version yesterday with this configuartion… i had not problems…

5

I reinstalled your entire list of setup files but still same

You have DebugGame target configured

  • Try to set developer or shipping target

  • Delete (Intermediate, saved, binaries) folders and generate visual studio project files.

  • ÂżAre you migrating from a blueprint project?
    if so… Create a new C++ project and migrate the content folder to the new project.

-Verify your instalation

-Verify MSBuild version.

-If nothing of this works you really need professional help. I’m sorry!!

I did not solve the error, but I needed to compile my plugin for version 5.3. So, I set up a virtual machine to achieve this, and everything worked very well. I guess my Windows setup is somehow broken, possibly due to environment variables or registry issues.

OMG I Fixed the issue after 2 days :slight_smile:

Just remove the BuildConfiguration at C:\Users@Your Username@\AppData\Roaming\Unreal Engine\UnrealBuildTool

I got the same problem,too. It troubled me 2days ago.

Not working ffor me, if I want to build the whole project it works, but if I want to build a plugin using “Compile Current Module” it says “Unable to find file” … Upgraded UnrealVS Extension too.
