In VS 2005 with VSTO, windows form code to initialize a new Excel Workbook
object builds without error but fails in debug with "Retrieving the COM class
factory for component with CLSID {00020819-0000-0000-C000-000000000046}
failed due to the following error: 80040154."

I'm able to run the same code with Microsoft Access 2003 VBA module on the
same computer successfully.

Any suggestions?

I'm not sure, but I would try to reinstall the Office2003 Primary Interop
assemblys.
There is a dll for each of the different Office applications.
