as Native Instruments creates nki because we can only open it if we add the nicnt to kontakt I can generate an nki that will only open if I add nicnt like theirs

 

I'm sorry, I don't quite understand what you're trying to say.

 

Look for the Kontakt 6.6.1 Version from Bob Dule at the Sister Site .
There is a NICNT Maker and Patcher included, i think this is what are you looking for.

I can absolutely recommend this version

 

I want to create a library like the Native Instruments that only opens nki if the library is added to kontakt

 

I'm not aware of any Kontakt library that does not allow .nki files to be opened through the "Files" tab. I assume you're using Kontakt Player?

 

it need a Native Instrument license to make what you are asking to = a commercially locked nki.
your library need to be integrated to NativeAccess.xml and NKI protected by a jwt license. it have a cost.

the other way to lock instrument it is to make a script protected resource, as realitone or hammer & waves. but it can also been unlocked.

nobody will help you to make that kind of thing here. you d' better check the scripting part of the Ni forum.
but is is funny.
