A full download of the latest version of the library is made available to you when:
All libraries, including the ones not listed above, can be downloaded directly from your browser as a single ZIP file. These direct links can be found at the bottom of the download instructions in your ProjectSAM account.
It is important to make a safe backup of your purchase. While you get multiple downloads per license and are allowed to request additional downloads if needed, the fastest way to restore an installation is to simply have a local backup of the library folder in question.
If you downloaded the library using the ProjectSAM Downloader, it is now time to install and activate the library so that you can start using it in Kontakt, Komplete or Maschine. If you downloaded using Native Access, this has already been done for you.
