It looks like missing "import pythocom (from....)" ...

You should uncomment the "_reg_clsid_.." line,
generate the GUID once, 
( type 'import pyhtoncom' and 'print str(pythoncom.CreateGuid())'
  at the python command line)
and insert it in the code.

As far as I understand your code, you will get different
GUID's with each invokation, which makes no sense.

The 'print' makes no sense in the class definition.

Greetings, Uwe.
