And I do not understand why I found quisk v.4.2.23 installed in c:\users\my name\AppData\local\Programs... at the beginning of this attempt to repair and upgrade. I had always used the "pip install --upgrade quisk" command to upgrade it.
Today when I reinstalled v.4.2.23 it went directly in c:\users\my name\AppData\local\packages.... as v.4.2.24 does also.
