"PERSONAL.quicken" could not be opened. (Q mac)

Question

I used a Mac and recently upgraded to MacOS 26.2 (most current version). Now when I try to open Quicken for Mac I get an error message to check my version. I am running the latest version 8.4.1 but still get the message. I tried to reinstall it but get the same error. Also tried to use the most recent backup and it still fails. TIA. Jay
