UE 5.3 errors when building engine

Development Getting Started & Setup
,
1

Hello,

I’m trying to build Unreal Engine 5.3 from source, but I get a ton of errors with the UnrealBuildTool saying it fails to compile.

Here’s the output after running GenerateProjectFiles.bat:

Setting up Unreal Engine project files...

RunUBT ERROR: UnrealBuildTool failed to compile.


GenerateProjectFiles ERROR: UnrealBuildTool failed to compile.

Things I’ve tried:

  • Downloading the engine from scratch and starting fresh (source and launcher versions)
  • Installing UE 5.3 from the Epic Games Launcher (which works, but when I try to compile any C++ project I get the same errors listed above.
  • Reinstalling Visual Studio 2022

Other things to note:

  • I only have VS 2022 on my computer, not 2019
  • I have .NET 6.0, 8.0 and 9.0 Runtimes installed
  • .NET Framework 4.62 targeting pack is installed
  • .NET Core 3.1 is installed
  • Windows 11 SDK (10.0.26100.0) is installed
  • MSVC v143 x64/x86 build tools are installed

Any help is greatly appreciated!
