I am running Quicken Classic under MAC OS Sequoia 15.1. When Quicken starts it prompts for an update from 8.1.0 to 8.1.1. After acceptance it tries to install 8.1.1, fails, and then loops back to 8.1.0, but prompting me to update again. After several tries I eventually decline the update, and it reverts to normal behaviour under 8.1.0. Thanks in advance for any suggestions.
