you for reaching out to the Community regarding your issue, although I am sorry
to hear that you are experiencing issues with updating your Quicken. I'm wondering here do you get this error consistently when trying to update Quicken? Have you tried restarting your computer then seeing if you're able to update? Additionally could we get the exact error as that will make it a bit easier to see what could be causing the issue as well.
Once you get the chance please let us know more and we'll see what we can do to correct the issue.
