I am learning. After 35 years of Quicken, I am learning. After Microsoft pushed through an update on my computer yesterday morning, Quicken would not update. I did all the regular actions, shutting down, restarting, up to 3 times. Then I looked at recommended fixes (I haven't learned to ignore these from Quicken). I tried to update each account separately to find out which one was causing the issue. Turns out, they all were.
I gave up and waited until today, 7/16. Now all is fine. I'm sure that someone in Quicken fixed it, but no one will admit the problem. Getting old and lazy works!
