After upgrading to R28.24, I can no longer open Quicken successfully. My register opens but it immediately tries to get me to log in several times before getting the attached image, so it recognizes my account, but not that it is already installed. It wants to to download the software and finish the installation.
I have tried validating the file and did a complete uninstall including QCleanUI and still get the same error.
I have tried new data files, same issue.
I have tried a commercial uninstaller and getting rid of all Quicken folders, but no go.
I have been able to install successfully on a tablet without issues, so the update corrupted something on my laptop.
