So, I have python 3.9.7 installed. When I installed it, pip had also been installed.

I checked if python is installed (Windows) using "python --version". The Problem: When I try the same with pip; "pip --version", an error occurs saying that the program can't be executed (command prompt)

Does anyone know why?

You can try to reinstall pip. This my solve the issue. Use can either install it over command window with 'py -m ensurepip --upgrade' oder download the 'get-pip.py' file (check https://pip.pypa.io/en/stable/installation/).

Try this first Did you added python to PATH? This is also important. Check https://datatofish.com/add-python-to-windows-path/ to do so

Make sure that the python version is the version of your intent.
Windows python installer sometimes defaults to py for newer python installations.

python --version

Then try to install for example openpyxl package, with admin access, if required

python -m pip install openpyxl 

Have you already tried pip3?

pip3 install openpyxl
