If you've installed your Expansion Packs correctly they still aren't showing up then try the following:
First, open Kontakt, click on the arrow next to your library, such as EXHALE, and choose Open containing folder.
Check to see if your Expansion Pack presets are present in the following location:
EXHALE > Library Data > EXHALE Presets
Expansion presets are denoted by a three-letter prefix, such as AMB. for the "Ambient Vocals" pack.
If they're not there, that means the Expansion Packs were not installed in the correct folder or you may have a duplicate copy of your folder. Duplicate folders are often created when a user installs the library from Output Hub, and then installs it again accidentally through Native Access during the activation process.
This duplicate folder can be commonly found in your shared folder:
Mac: Macintosh HD/Users/Shared
PC: C:/Users/Public/Public Documents
If this is the case, you'll have to delete the duplicate copy by simply dragging it to your trash. Next, open Native Access and locate your library under the Installed products tab.
Next, click on REPAIR and choose RELOCATE.
Doing so will prompt the following:
From there, follow the on-screen instructions to relocate your library which contains the Expansion Packs.
You can now reopen Kontakt, perform a SCAN, and your Expansion Packs should be successfully displayed.
