Windows 10 Fall Creators Update Fails

This is a long shot. Have two machines where update/upgrade fails with a report that "novell network client" needs to be uninstalled. Problem is these machines have NEVER had any version of novell network client ever installed. BUT, both machines HAVE run the GWProfileSetup utility for creating a GMS conduit for Microsoft Outlook. ... Could this utility have installed files with names that the upgrade routine sees as "novell network client"? If so, is there a way to identify them and uninstall them?
