What is your OS?
Did you get this solved?
It sounds like you are missing elements for your PATH variable so the OS can find both the python.exe and its libraries.
- My Python is installed in
c:\program files\python3.14 - Here’s what I have in my Windows 11 PATH variable (in my cmd.exe window) pertaining to Python:
;"c:\program files\Python314";"c:\program files\Python314\Scripts";"c:\Users\YOURUSER\AppData\Roaming\Python\Python314\Scripts"
These locations are also set up in my system path under: Control Panel, System Properties, Advanced tab, click Environment Variables button.
