Quick question: Have you considered installing on WSL? I have had much
better luck with that on Windows.

This seems to be an incompatibility of ParMetis Windows support and your
version:

G:\VisualStudio2022\VC\Tools\MSVC\14.37.32822\include\stdint.h(37): error
C2371: 'int_fast16_t': redefinition; different basic types^M

G:\mypetsc\petsc-3.24.1\arch-mswin-c-opt\externalpackages\petsc-pkg-parmetis-f5e3aab04fd5\headers\ms_stdint.h(80):
note: see declaration of 'int_fast16_t'^M

G:\VisualStudio2022\VC\Tools\MSVC\14.37.32822\include\stdint.h(41): error
C2371: 'uint_fast16_t': redefinition; different basic types^M

G:\mypetsc\petsc-3.24.1\arch-mswin-c-opt\externalpackages\petsc-pkg-parmetis-f5e3aab04fd5\headers\ms_stdint.h(84):
note: see declaration of 'uint_fast16_t'^M


  Thanks,

What most experimenters take for granted before they begin their
experiments is infinitely more interesting than any results to which their
experiments lead.
