Version 2.72. This addon: http://pasteall.org/56112/python
I coped the code and pasted it into a notepad doc, saved as a python file.
I have tried installing through the installer, then manually have moved the file into C:\Users*Username*\AppData\Roaming\Blender Foundation\Blender\2.79 and F:\Blender\2.72\scripts\addons
My Blender is in the F directory rather than C.. is this complicating something? Basically the file is not showing up for me to check the box to activate it.
