Does Native Access Replace Service Center?
Native Access offers activation, downloads, installation and updates for all your registered NI products from a single place. However, given the long history of Native Instruments products, upon the release of Native Access not all products will be supported and you may find that one of your older products or products from third-parties are not displayed. For these products, Service Center will still be needed. All future products will be managed by Native Access exclusively.
