Hello, I downloaded the Unreal Engine 5.1 source code from GitHub and ran the Setup.bat file. After all the downloads were complete, when I run the GenerateProjectFiles.bat file, I get an error saying ‘Unable to find valid latest C++ toolchain for VisualStudio2022 x64.’ In the tutorial I followed (https://www.youtube.com/watch?v=jFe37SviLk8), I selected and downloaded all the tools and components of Visual Studio (when reinstalling Visual Studio). However, it didn’t work in any way, and I don’t know exactly what to do. Can someone help?
When I run the GenerateProjectFiles.bat file for Unreal Engine 5.1 source code, I encounter an error
hi @IsmailKermeli ,
The error is caused by UE5.1 not supporting the latest version of VS2022.
I suggest you use my corrected version and the latest 5.3 version

You only need to build an older source version is you have compatibility version problem for a plugin
Ah, my friend, I think I’ve solved the problem, but I’m not sure how effective it is. Now, in the code of the file at the path Engine\Platforms\Hololens\Source\Programs\UnrealBuildTool\HoloLensProjectGenerator.cs, specifically at line 87, the code for the file on that path looks like this:
DirectoryReference? PlatformWinMDLocation = HoloLensPlatform.GetCppCXMetadataLocation(Compiler, “Latest”, WindowsArchitecture.x64, Logger);
However, I overcame the issue by replacing “Latest” with “Preview.” I hope this works for server processes in the future and doesn’t give me different errors. I hope my modification is correct.

You answer is correct my friend the latest versions are all “Preview” and hence the build number does not exist. Good Luck
