Alicia's Keys isn't included in Komplete 15 Standard, you need K15 Ultimate or Collector's Edition. You can find a list of what's included in each version here - https://www.native-instruments.com/en/products/komplete/bundles/komplete-15-standard/compare/
If you like bundles then the best option is to upgrade your bundle to a higher tier.
