When installing a Kontakt samples library (most of them are now bundled with Kontakt Player 2) from an OSX partition (for example Tiger, less resources demanding for graphics and Altivec on a G4), we would like to be able to run it also from another OSX version (for example a Leopard partition, on the same machine). However the Kontakt patch files (.nkc) that have been installed from the first system seem encrypted (probably with the systemId) as they can’t be used from another system partition : Kontakt Player says encrypted patch cannot be loaded until library is registered properly.
The fix is to copy all preferences files created by the initial intallation (on the first system partition) to the other OSX partition : these files are located in Library/Preferences (com.native-instruments.Content.plist, com.native-instruments.Ethno World 4.plist, or com.native-instruments.KontaktPlayer2.plist for example) and also in Users/accountName/Library/Perferences (com.native-instruments.KontaktPlayer2.plist, Content.plist). If the libraries stop working after this, just replace the Content.plist with the one provided on NI forums site (or soundsonline site support area).
