VolvoGirl, THANKS! This is the most promising lead I've seen after multiple web searches over the past year! Once you provided a toe-hold for me, I pulled on the thread a little and found the following URL:

It's basically what you provided, but more formally spelled out. I thought I'd add it in case anyone stumbles over this posting. The only hiccup was that it took me 5-10 minutes to realize that ProgramData was a hidden folder. I've uninstalled all the MSI's for the unneeded state. Now I'll await another TT update and see if I dodge the state update. 8^) Thanks for this "difficult to find" information.
