Actual behavior

Third party programs (Plaxis) has installed Python, but these versions are not shown in the intepreter selection unless they are first in the list from the Windows Path Environmental Variable. If I change the order, once again only the first listed path is shown.

All Python interpreters in the Path should be shown.

Steps to reproduce:

1. Have multiple Python interpreters installed under Program Files.
2. Reorder PATH to only shown the first version in VS Code.
