The requested operation requires elevation---solutions?

When trying to insert a reference into word I get “The requested operation requires elevation” error.   I am using endnote 9.3.3 and MSword 365 (v16.o.13029.20232) on windows 10 pro (1909)

I have tried suggestions in this thread   

These suggestions does not resolve the warning.  To summarize what i have tried:

  1. Running both programs as administrator

  2. running both programs with user privledges

  3. chaning UAC to its lowest setting

  4. UAC at lowest level and trying #1 and #2

  5. setting endnote to run in windows 8 compatability mode 

Does anyone have any further suggestions?
