Yes. DesktopPlayer is an add-on that offers the ability to run your corporate Windows virtual desktops locally on Windows laptops and MacBooks, but you still need licenses for rights to the Synchronizer, which is used to deploy and manage the virtual desktops. Synchronizer licenses are included with Citrix Virtual Apps and Desktops Enterprise/Platinum.
If your users are already licensed to use Citrix Virtual Apps and Desktops Enterprise or Platinum, you do not need to purchase additional Synchronizer licenses. However, additional DesktopPlayer add-on licenses are required. If you do not have Citrix Virtual Apps and Desktops Enterprise or Platinum, you must procure the appropriate license for the Synchronizer and the DesktopPlayer add-on license.
