Tested on windows11 and works. I notice that the artifact for the Windows Installer / WindowsInstaller (pull_request) CI did not build against python3.12 so tested with python3.11

I think this PR is ready to merge if the CI neuronsimulator.nrn Failing after 60m — Build #20240704.22 failed can be fixed.
