Don't know. Seems like different things work for some and not for others. For me, the manual update didn't work. I had to uninstall/reinstall. Removing the "Deluxe 2019" folder before the reinstall as mentioned above seemed to do the trick for me, but also required me to copy over my state folder from the original "Deluxe 2019" to avoid paying for the state again.
But maybe I just got lucky and this won't work for others. The whole thing seems pretty flaky in general.
