Python version is being overridden


I try to install Python 3.10/3.11 on my Windows 10 machine. It works without any issues, but when I try to execute code from the terminal, it uses version 3.6.6. (Even though version 3.6.6 is not listed in my Python versions.)

C:\Windows\system32>python --version
Python 3.6.6

C:\Windows\system32>py --list
 -V:3.11 *        Python 3.11 (64-bit)
 -V:3.10          Python 3.10 (64-bit)
 -V:3.9           Python 3.9 (64-bit)
 -V:3.8           Python 3.8 (64-bit)

I tried editing my environment variables, and it looks just fine for version 3.11 (user Path):

When searching for Python 3.6 on my computer, there's a software called 'PsychoPy' that uses Python 3.6 (which I need):

Is it possible that the software is overriding my Python version?
Any idea how can I solve this issue?


Solution

  • Run set PATH in your terminal to check the current PATH variable in CMD. You should see that the path to the Python 3.6 executable is near the front.

    You are showing your user PATH variable, but there is also a system PATH variable that takes precedence in the PATH order. You can find the system PATH variable in the bottom pane of the Environmental Variables window.

    If it is not there, it could also be an AutoRun process that fires everytime you start CMD. That is controlled by a expandable string value AutoRun at the registry key

    HKCU\SOFTWARE\Microsoft\Command Processor
    

    If it is present, then the data attached to the AutoRun value is executed everytime CMD starts. This could be used to place the Python 3.6 as the alias to python
