I'll rescind my assertion that everything beginning with "Evolution" is player-compatible and NI-registerable. I've verified that it does not apply to the Rick bass, as indicated by the non-ambiguous "Full version of Kontakt required" notice on the product page.
Here's what I don't understand: shouldn't any library that's compatible with the Kontakt player show up in Native Access for registration? For example, Evolution Strawberry's page says "Kontakt player included", suggesting it's player-compatible, but it's not listed in Native Access.
