No Python 3.10 installation was detected

[snippsat]

Look at this Thread and Python 3.9/3.8 and pip installation under Windows

Problem was, it did not replace 3.9.7, but installed besides it, giving me two active installs.

It will not replace so it install to new folder.
All install is passive Windows see Python trough Environment Variables Path.
So if not Path update you can do it manually as in this image
Then python and pip from command line will point to 3.10.

py can be used to access all version for python.org.
As you see i have many still python 3.9 as main version and can access 3.10 with py
