I finally succeeded with Tech Support Simon's help.
But prior to this I spent DAYS searching and on forum, Google, Youtube videos, etc. to no avail.
Was not crystal clear how to go into Options/MIDI and proceed getting the Kontakt dll installed. Lots of advice, instructions about how I might be using 32 bit Kontakt, how/where to find VSTi's, and on and on. I could get other DXi's and VSTs installed but not any Kontakt libs until recently.
