Store Migration Error

Question

I can’t open Quicken 2015 on my Mac. Bought the upgrade and now it says Store Migration Error. How can I get my data?

That's not why I asked the question.
ISTR reading posts about Q Mac 2015 not running under Catalina.
I also remember posts in the Community from a few years ago about "persistent store migration error" in Q Mac 2015 (or 16 or 17).
A little searching of the Community might find you an answer.

@UKR There is no purchase involved in upgrading the macOS; those updates are always free. I think it's clear the purchase was the current version of Quicken. What I can't tell is whether the error comes up trying to open Quicken 2015 (as reported: "I can’t open Quicken 2015 on my Mac") or in trying to update Quicken 2015 data to the newly-purchased current version.

Which upgrade did you buy? The Mac OS upgrade to Catalina?
