Can't upgrade from Python ≤3.9.6 to ≥3.9.7 #1

Closed adang1345 closed 2 years ago

Due to https://github.com/python/cpython/issues/96729, the GUIDs of the installer change between Python 3.9.6 and 3.9.7, making it impossible to upgrade across this gap. The installer for Python ≥3.9.7 will fail to recognize that there already exists a Python installation and will instead require a new, side-by-side installation.

I have uploaded fixed installers.
