As a couple of guesses, I'd ensure you do this from an elevated process
(ie, "run as administrator") and also be sure to use fully-qualified paths.
(The error code shown appears to be ERROR_INVALID_POINTER, but that
might be a red herring)

I'm not at all versed in win32com programming... any help please?

This sounds more like a problem with your approach to servicing your
product, and not necessarily a python windows specific problem.
I can point you in the direction to create the firewall exception,
but you would still need to figure out how to arrange to have the
code actually execute.
Windows Firewall rule exceptions don't appear that hard to define.
Windows Firewall COM interfaces docs:
http://msdn.microsoft.com/en-us/library/windows/desktop/aa366449(v=vs.85).aspx
Some simplistic VBScript examples of using those interfaces:
http://msdn.microsoft.com/en-us/library/windows/desktop/aa366421(v=vs.85).aspx
I'd use the VBScript examples as a base and determine what kind of
exception is best for your needs. (i.e. as little of an exception as
possible)

We have python running on a number of devices in the field and
have experienced problems where it appears that a windows update
has removed a windows firewall exception, blocking our python
service from operating.
Has anyone else experienced something like this? Is there a way
to fix it without human intervention?
