I have just installed Python 3.9.10, it seemed to be working fine until I tried to install a package with 'pip' I got this error message: "System cannot execute the specified program". I then tried executing this command "python -m pip --version" that resulted in this: screenshot of error message.
I made sure to add python to the system's PATH and also tried uninstalling and installing again but to no avail. I would appreciate any help, thanks in advance.
