How Do I Add a Player Library in Kontakt 5.6.8 or Later?




  • Mike Bryant

    What if the product comes with no serial number (as in the case of Sacconi strings)?

  • Luke

    Hi Mike,

    If a product comes with no serial number this is likely a 'non-player library', meaning that you'll need to load the instruments directly through the 'files' tab in Kontakt.


  • R Neylon

    These libraries - without serial numbers - load as "demo" versions. What to do? Please?
    I can run two stand alone versions of Kontakt - ie one that works with the two libraries I have with serial numbers and one that works with all the others - but I cannot load two versions of Kontakt as plug-ins in Logic Pro. Can I?

  • Dexter Garcia

    How do you add a library without a serial number? I just bought the Martyn Ware library for $99 and I can't even figure out how to add this to Kontakt.

    @Luke seems like R Neylon needs an answer too...

  • Sandy

    Hi Dexter and R Neylon,

    Libraries without serial numbers are those which require Kontakt full (not Kontakt player) Please see a quick guide on how to use these libraries here:

    R Neylon, there is no need to run two versions of Kontakt, the latest version of Kontakt full will work with both types of library.

    Hi, I only have nine letters to authorise and I cant add a serial as I need more letters?

  • Sandy

    Hi Ray

    It sounds like you are looking at your order reference and not your serial number, you should have received this number in your download ready email but it can also be found here whilst logged in.

  • Olivier Poeydomenge

    my serial doesn't work. They say "the serial doesn’t belong to a known product…"

  • Yuri Gore

    Mine also says it's a demo and times out. Is that because I'm using kontakt player? and not the full kontakt?

    Hi Yuri,

    Hi, how can we see solo strings in Komplete Kontrol ?
    because there is no previews sounds in kontakt ..


    Oh sorry, I just had to open Komplete Kontrol outside my DAW and rescan the library ^^

    But I still have this problem with LABS plugin and it's not solved !

  • Ryan Holladay

    I am trying to load the LABS instruments into Kontakt, but there are no files that can be identified by Kontakt in any of the folder (the closest things are .multi -- no .nki or anything like that). I've repaired the folders and nothing has changed. What am I missing?

  • Sandy

    Hi Ryan

    The new LABS are not Kontakt based at all, please see our getting started page for the LABS plugin here

    i downloaded the Kontact and cant load my library! HELPPPPP - its on an external hard drive - what do the settings need to be !??!

  • Zachary Moore

    Hello! I purchased scraped percussion (which says you need a full version of Kontakt to run. I have a full version of Kontakt; however, no serial number came with my purchase. Can you please help me out? I would love to work with a better interface for this instrument. It sounds lovely.

  • Sandy

    Hi Zachary,

    Scraped percussion is what we call a "non-Player" library meaning it is not added like the guide above, instead you need to follow this guide to load instruments from the library:


  • Jason Savory

    I've seen it asked many times but not effectively answered, I too am getting the error that my serial (studio strings pro) does not belong to a known product. This is very frustrating as I purchased this library for a time sensitive project!

    EDIT: Native access installed kontakt player 6 (I also have kontakt 5.8.1) both of which are advertised to work with this product.

  • Peter Martin

    Hi, I've just had a computer crash and am trying to get my percussion library up and running on a new computer. I'm trying to register with NA but it won't accept my serial number. It tells me it's already registered. Do I need a new serial number from you guys?

  • Sandy

    Hi Peter

    You will see the "already registered" error if you try and register to a different NI account than you used initially when registering your serial. Since the license is for a single user, it can only be registered on one NI account.

    If you're having difficulty with which NI account you used or think it might have been registered in error please open a support ticket with us and we'll be glad to help you get back up and running.
