These steps from MS08-069 seemed to have resolved the issue. Thank you.
The following security updates do not support the complete removal of MSXML
Security update 954430 for Microsoft XML Core Services (MSXML) 4.0
Security update 936181 for Microsoft XML Core Services (MSXML) 4.0
Security update 936181 for MSXML 4.0 Service Pack 1 (SP1)
Security update 936181 for MSXML 4.0 Service Pack 2 (SP2)
This situation occurs because this version of MSXML is installed in
side-by-side mode. To work around this issue, follow these steps:
Remove security update 954430 by using the Add or Remove Programs item in
Delete the Msxml4.dll file from the %SystemRoot%\System32 folder.
Repair the previous installation of MSXML 4.0 by using the Add or Remove
Programs item in Control Panel.
The earlier versions of the Msxml4.dll file and of the Msxml4r.dll file are
restored to the side-by-side folder and to the %SystemRoot%\System32 folder.
I checked for updates although Windows Update said my system was up to date
and then downloaded 954430 presented by Windows Update.
I did not receive the potential error message referenced in the article.
