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?
@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.
