To properly install a library, please refer to this page.

KONTAKT Player is the free version of the Kontakt sampler software. You can download it here.
It works with libraries that developers have paid a license fee for. NKS compatible libraries are fully usable with this version. For non-licensed libraries, the full KONTAKT software is required.

KONTAKT is the full and paid version of the software. It can loads any licensed and unlicensed library.

It depends on the library. To know which one are, look for the mention "Works with KONTAKT Player" on the product page.
A libraries that only has the mention or "Full KONTAKT needed" doesn’t work with the free KONTAKT Player.

If you are seeing the word ‘DEMO’ written on KONTAKT, one of a few things can be occurring :

Non Player library
If the library doesn’t work with the free KONTAKT Player software, it will only run in ‘DEMO’ mode meaning you will be bale to use it for fifteen minutes. After that, there will be no sound on the output, and you won’t be able to access the editing features.
To solve this problem, you will need to upgrade to the full version of KONTAKT.

To know which version of KONTAKT your library is requiring, look for the mention "Works with KONTAKT Player" or "Full KONTAKT needed" on the product page.

Player library
Due to errors in Native Access, Player libraries can sometimes run in ‘DEMO’ mode, even if correctly authorized. In Particular on Mac OS.
Follow the steps bellow o resolve the problem :

- From the location, HD/Library/Application Support/Native Instruments/Service Centre remove the .xml file for the library, Kontakt and Native Access.
- Delete from the location Mac HD/Library/Preferences - Kontakt and the Library.
- Reinstall Kontakt from Native Access, then add the relink your library from Native Access.

Sometimes certain files in the above locations might be missing, for example the XML for a library. That is ok, and continue without deleting that.

If you didn't receive a serial number after your purchase, it is probably because the library you ordered doesn't come with one and needs the full paid version of KONTAKT to work.

These libraries are not authorized on Native Access.
To use them, simply download the files sent by email after your purchase and you will be good to go.

To now if your library needs the full version of KONTAKT, look for the mention "Full KONTAKT needed" on the product page.
