Ok, after converting a python program to an .exe with py2exe.
The program will run on a computer with Python installed on it no worries, however if python is not installed it starts and finishes in the blink of an eye. even with
raw_input('Press Enter to exit ') added.
The program is the one that works out mileage for cars that I changed to aus things from a tutorial on the net that i can't find anymore.
