Windows

1. Open a DOS box (Command Shell, MSDOS Prompt, or whatever they're calling it these days).

2. Go to the directory created by expanding the archive:

   cd <archive_directory_path>
   

3. Install the package:

   <path_to_python.exe>\python setup.py install
   

If your system is set up to run Python when you double-click on .py files, you can run install.py to do the same as the above.
