Transfering a Komplete Kontrol preset for a third party Kontakt instrument to another computer. This took a bit of trail and error but it should work. I have tested it by moving the library folder to different locations on my computer but I have not tested it on a second computer.
Once you have saved you preset in Komplete Kontrol look in the folder
C:/Users/[user name]/Documents/Native Instruments/User Content/Kontakt/ You should see a sub-folder with the name of your instrument. In the folder should be a *.NKSN (if you have saved several pre-sets from the same NKI file there will be more than one.)
Copy this folder and its contents to
C:/Users/[user name]/Documents/Native Instruments/User Content/Kontakt/ on the second computer.
You will need to have the library installed on the second computer, Copy the related NKI file (this is be the one where you assigned any host automation) to the library on the new computer.
Open Komplete Kontrol software on computer 2. It should detect the new NKSN file and it will show up in the USER section of the browser, if not make sure
C:/Users/[user name]/Documents/Native Instruments/User Content is in the scan path (its default so it should be, but....)
Open the preset from the browser, unless the folder structure and names are identical on both computers you will see the Kontakt missing files dialogue. You will need to run this twice, first to find the NKI file and then to find the samples. Once the samples have been loaded make sure you are in Komplete Kontrol's edit view (ie the full Kontakt interface is visible) and re-save the NKI, then go to Komplete Kontrol's file menu and re-save the preset (NKSN) file.
Next time the preset should load without issues.
Bear in mind the NKSN file contains a path to the NKI file so its important not to rename the NKI.
