ValueError: Not a valid python path: 'C:/Program Files/Python351/python.exe'

Here is the output of pipenv --support | clip: The path which is causing the error may have existed on my Windows 10 PC, but thefolder C:/Program Files/Python351 no longer exists on my PC. I do not understand where pipenv finds a reference to this non-existing folder and I do not know how to solve this problem.

I have been successfully using the following command to create a virtual env for several new django projects: pipenv install django>=3.0 but now running this command gives this valueerror.

I will very much appreciate a solution to my problem.

Anyone facing a similar error needs to uninstall old python versions C:\Windows\regedit.exe HKLM\SOFTWARE\Python\PythonCore
HKCU\SOFTWARE\Python\PythonCore\

My advice to you: look for Python351 in regedit (win+r , regedit) and delete the entries (their content)
