I finally got the 2020 Deluxe to install. 

My Solution: Ctrl+ Alt + Delete, Task Manager, More Details (at the bottom), Click Processes, then scroll down under Background Processes and find Intuit Update Service. Click it and then click End Task.

I was then able to fully install the software.

Thanks, worked like a charm,  had to stop the service to get it to install AND to get it to manuel update after.  Big hiccups this year.  Quite stressful when working on taxes!

A new member to the TT forum is able to post a fix that works. While the experts fumble with the repeated failed fixes.
