Problem with vswhere.exe

[Ilmari Lauhakangas]

It seems there is some recent issue with vswhere.exe that is making the 
invocation in our configure.ac give blank output. This is now affecting 
three newcomers.

Mike Kaganski has been providing assistance and we have double-checked 
screenshots of Visual Studio installer. The installers show the right 
components, but this command outputs nothing on the affected systems:

"C:\Program Files (x86)\Microsoft Visual Studio\Installer\vswhere.exe" 
-prerelease -version "[ 16 , 17 )" -requires 
Microsoft.VisualStudio.Component.VC.Tools.x86.x64 -property installationPath

This happened both with VS2019 and 2022.

Any ideas on how to troubleshoot this?
