Occurs when you try to run a macro in Excel 2010?

Answer 1

This means that the dll with COM objects finds and loads,
but then the class factory from this dll does not find it when you request the coclass you need.
Possible reasons:
- Registered a new COM library that does not have the required interface, and forgot to clean up the old registration.
