Thank you bsr001 for your suggestion to "run as administrator" as it worked for me.
I read through all of the entries in the thread and was hoping for a quick solution. I first tried the proposed solution by Grupper, but I was not able to stop the MSIserver. So I exited all programs, my windows user, and log in as the Admin. I noticed Windows 10 did some updates but not sure what they were as I walked away to get coffee. I tried to kill the MSIserver but still did not want to allow me to do it. Reading through all the thread entries, I noted 7 solutions:
1) Update the .netframe stuff
2) Update manual per a TTX webpage suggested by a user
3) Update Error 1719 per a TTX webpage suggested by a user
4) Run as an Admin
5) Try update with Firewall off
6) Uninstall and reinstall in safe mode
7) Wait through TTX Updater message and see if TTX install updates properly
So I restarted the computer, login my windows user, opened / ran TTX 2019 as administrator, and voila!!! - it worked - the updates progressed and completed as normal!
