Hi Kevin,
You shouldn't put your files inside the Program Files directory, it's protected by the system. Instead, you should create a directory (my suggestion) 'git' in your user's directory.
Inside this directory you should create the directory that will organize your code.
After that you need to create a virtualenv and installl all Python packages required in the virtual environment.
Most Python IDE (WingIDE, VS Code, PyCharm, Eclipse, etc) supports virtual environments.
On Windows you have different options to install Python (Direct, Anaconda, CygWin, etc) and create the virtual, the best would be to use a Linux or Unix based system. Consider a virtual machine on VirtualBox with a linux distribution.
Even if you are able to run as admin, you could create security issues.

André
