Thank you for your response. When I followed your advise, the update did show as installed.
I have been unsuccessfully trying to install Quickbooks Pro 2018 and thought it might be the uninstalled update. The error message I get every time is 1935, software requires the Microsoft .NET Framework to be installed. I checked all the system installs, and 3.5 and 4.7.1 show as installed.
thank you for your help
