Script not found when using pyinstaller

Question

I am trying to convert a python script to an exe file. I have added the python script to a folder together with pyinstaller, and I use the right PATH in CMD:

This is what it shows.

I know there are some similar questions here, but I have not found a solution yet.

Answer 1

I found the solution. I had to first install Python from their own website instead of the Windows store. Then I had to add it to a PATH. After this it still did not work because I used Python 3.8.0, so I had to install pyinstaller development version.
