Symptom
After updating your Kontakt libraries, you cannot load them in Kontakt anymore. In most cases, you receive the error message:
Your version of Kontakt is too old to load this file.
Cause
Many of our products received an update for NKS2 compatibility and polyphonic aftertouch. These library versions require the latest Kontakt 7 (Player) in order to run correctly.
Solution
The latest Kontakt 7 (Player) requires macOS 11 or higher / Windows 10/11.
There are different solutions depending on your setup:
- If you are on macOS 11 (or higher) and use Kontakt 7 (Player), please install the latest update in Native Access.
- If you are on macOS 11 (or higher) and use Kontakt 6, you can install the free Kontakt 7 Player and use it instead - or you can install the previous versions of the affected libraries via the following link: Kontakt Libraries - Previous Compatible Versions
- If you are on macOS 10.15, you cannot install the latest Kontakt 7 (Player) since it's not compatible. Please install the previous versions of the affected libraries via: Kontakt Libraries - Previous Compatible Versions
- In case you simply prefer using Kontakt 6, please install the previous versions of the affected libraries via the following link: Kontakt Libraries - Previous Compatible Versions
If you have downgraded the affected libraries, please run Native Access once so that the libraries can be authorized correctly.
