I'm sure I've seen a checklist somewhere for what to do to get COM working,
but I can't remember where. Here are a few of the basics:

1. Make sure that the IUSR account has proper NTFS permissions on the COM
2. Check the System Event Log for any strange looking COM/DCOM error
3. Make sure that the component is propery registered... You may want to go
and weed out all of the multiple entries in the registry (at your own risk).
4. Reboot!
5. Pray for a more helpful error message.... :o)

That seems to be normal.  Mine's the same (no one in the list)...except it
works :o)

No, but it is an awful lot to tackle in one day.
