You could change the code to use late binding to Excel, then the library entry doesn't need to be checked.

Declare the Excel app as an Object and use the numeric values of any Excel specific commands. There is an example of Excel being used this way on my web site at Extract Data from E-Mail. The code there is for Outlook, but the principles for Word are identical.

Thank you for your quick reply and helpful link @gmayor. Before my response, may I point to a typo in Extract Data from E-Mail A paragraph (fifth one, I believe) begins with a double-"T": "TThe basic process will..."

The article is very slick. And I understand most of it. But I think I've asked the wrong question. I now remember I have many "Quick Parts" that I doubt migrated with the document. So, though "late binding" may take care of the Excel issue, the application will remain unusable.

My solution probably requires a better migration strategy. Particularly if my machine ever crashes.
