Thank you for the response and the additional details.
I would recommend signing out and signing back into the Quicken program. To do this, please follow the steps below.
Go to Edit > Preferences > Quicken ID & Cloud Accounts
Click sign in as a different user
Type "yes" to sign out
Sign back in using your existing Quicken ID
Once this has been completed, please attempt to update once more and let us know the results.
If you haven't
rebooted Windows since you installed the latest software update, please do so
now and then try Quicken again.
Still not working?
Let's do some
"Troubleshooting 101" to ensure the Quicken software is installed and
updated properly and that your data file is in good working order. Crashes or
killing Quicken may damage the file.
Please perform all the steps in this document in the order specified, even if
you have done some of them before:Troubleshooting
