Python win32com com_error: (-2147418113

[g.franzkowiak]

I'm trying to use a proprietary windows software with COM and win32com.
The result is everytime the error message

com_error: (-2147418113, 'Catastrophic failure', None, None)

I've read this in some e-mails, but can't find the solution and I have
not enough experience with Windows and COM.

Can anybody help ?

This ist the test script.

Usually this means the COM object has to run in a full ActiveX container.
You can host it in IE, or Pythonwin can act as a container with some effort.
See \pythonwin\pywin\Demos\ocx for some examples of using OCX objects
that require a container.
