py2FaceR was written on a Windows 7 machine running Python 2.7, so the author knows that it at least should work on there. py2FaceR should however work on any machine running Python 2.7. If it works on your machine please e-mail me so I can update these docs.
At the very least you need to install these manually:
Pip is the preferred method of doing the install, but easy_install will work too.
Once those Python and PIL are installed you can run pip install py2facer You may have to give the full path to pip (assuming you do the default install on Windows it should be in c:Python27Scriptspip.exe).
py2facer.py should be installed in your Scripts directory, so for example c:\Python27\python.exe c:\Python27\Scripts\py2facer.py should output some help text. The rest of the details are in Running py2FaceR
