If you have pip installed on your machine, it's probably because it's not found in your environment variables and windows doesn't recognize what you are trying to say by 'pip'. You have to tell it where to find it.

To add it to your paths, go to Advanced System Settings in the control panel/ settigs. Then Environment Variables > System Variables > Path > double click the value part, and in a new line enter your pip binary's location (probably C:\\Python33\\Scripts, but you may have another path).
