!!!SUCCESSFULLY RESOLVED!!!
Ah Fredo...you are a Genius...Thank you, Thank you, Thank you.
I downloaded and installed the new "PRIOR_SU2017_LibFredo6_v9.5k.rbz" file and will never know, or understand, what you did but it loaded and I now have the "LibFredo6 Settings" Menu under Window. I notice there is now an extra Extension listed called "top_LibFredo6 but there is no description or Version, Creator, and Copyright information given for it, the same as was happening before when I unsuccessfully loaded "LibFredo6"
I have also now loaded "Fredo6 Fredo Tools" and I can see I have much learning to do.
One small question arises because I see a number of references and opportunities to "Check for Updates" Am I being unduly concerned that a wrong update might get installed because I use SU 2016 or should I change the number of days to check, from 15 to 0?
Thank you again.
