not sure if anyone found the cure for this but the steps would be as such:
1. cancel out of the install piece
2. do a control - alt - Reset
3. select task manager
4. go to the services tab
5. scroll down to MSIServer
6. right click on the name and select stop
7. minimize task manager
8. select the start menu
9. right click on Turbo Tax 2019 and run as administrator
10. update should work
it appears that the Turbo Tax installer will wait if the Windows Installer service is running. One can not stop that service through the Service Administrative window and thus needs to be done through the Task Manager - Services tab.
