MSVC activation script location changed?

[h-vetinari]

I was trying to use vs2022_win-64 today, and this did not work. Looking closer at the output of the activation script, I see:

C:\Program Files\Microsoft Visual Studio\2022\Community>CALL "VC\Auxiliary\Build\vcvars64.bat" -vcvars_ver=14.38 10.0.22621.0
'"VC\Auxiliary\Build\vcvars64.bat"' is not recognized as an internal or external command,
operable program or batch file.

C:\Program Files\Microsoft Visual Studio\2022\Community>if 1 NEQ 0 (if "" == "" (CALL "VC\Auxiliary\Build\vcvars64.bat" ) )
'"VC\Auxiliary\Build\vcvars64.bat"' is not recognized as an internal or external command,
operable program or batch file.

Looking at the content of that path for my local setup (17.8.4), C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Auxiliary\Build does not contain any bat files anymore, just

Microsoft.VCRedistVersion.default.props 
Microsoft.VCRedistVersion.default.txt
Microsoft.VCRedistVersion.v143.default.props

Fresh environment (installed vs2022_win-64 ninja cmake):

That is indeed strange. I am probably asking the obvious, but just to check everything: did you installed the C++ part of Visual Studio? On new installations I sometime forgot to do so.

[h-vetinari]

did you installed the C++ part of Visual Studio?

Yes:

This was also working previously, though I can't rule out that a reinstall in the meantime has broken something 🤷

Also, if I click the "launch" button for the VS Build Tools in the VS Installer, I get a shell where cl.exe is available and environment activation works well enough to compile something (despite still not finding vcvars64.bat).
