You might want to look at PAMIE instead. It sounds like a Python
project that's aimed at automating Internet Explorer:
http://sourceforge.net/projects/pamie/
But if you really like COM, I found this tutorial:
http://www.evilbitz.com/2006/10/22/python-ie-automation-thorough-tutorial/
I'm not very good with COM, but I would recommend that you do some
research on it. From the traceback, I would guess that you don't have
administrator privileges (of some sort) on the machine you're running
the script on.
