title: Running cfx program for Firefox Add-on SDK on Windows
body: <p>I have downloaded Add-on SDK and executed <em>activate</em>.
  Python 2.7 is installed. PATH variable is configured properly and py files can run from anywhere.
  However, when i am trying to execute <em>cfx</em> (from Far command prompt, using the full path), i get the message: 'python' is not recognized as an internal or external command. How do i make it run?</p>
