Thank you for your assistance.  I have been out with pneumonia but got back and tried the fixes today.  The Quickbooks Tool Hub ran a load of repairs but did not fix my problem.  I went to the "fix error 1904" and repaired .NET Framework 4.8 (I did not see the earlier ones, 3.5 etc, referenced) but that did not fix my QuickBooks Pro Desktop either.  I will try your support team next.
