Something about permissions. Is this a problem with Windows?
3>C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Common7\IDE\VC\VCTargets\Microsoft.MakeFile.Targets(44,5): error MSB3075: The command "..\..\Build\BatchFiles\Build.bat -Target="UE4Editor Win64 Development" -Target="ShaderCompileWorker Win64 Development -Quiet" -WaitMutex -FromMsBuild" exited with code 5. Please verify that you have sufficient rights to run this command.
I was trying to compile with Visual Studio 2022. (Someone told me it should work the same, it didn’t).
I installed VS 2017 and used that, all the errors went away… Make sure you follow the instructions on the github closely, I guess.
