Bo Din helpfully created an earlier topic (see below), going through the Pianobook library and indicating which libraries are Kontakt 5, which should work with your Kontakt 6 player. I’ve had the same problem, but as I’m still using a Windows 32 bit system (until my computer dies – not any time soon, hopefully ;-)), I can’t update the Kontakt 6 player to the most recent version, as Native Access stopped working on 32bit a year or two ago.
All the Kontakt 5.8.1(R43) that’s available on Pianobook
