SOLVED! So the comments were right in that I had to change the directory to the location of the file, but what was missing was that I had to edit the system environment variable PATH to include the location of python.exe, which is my case was C:\program files (x86)\python27 but for most people is just C:\python27. Thanks everyone for all your help!
