This download is needed for administrators to set up activation for volume license editions of Office LTSC 2021, Project 2021, or Visio LTSC 2021 by using either the Key Management Service (KMS) or Active Directory. Long Description: Volume license editions of Office LTSC 2021, Project 2021, and Visio LTSC 2021 require activation. If you want to activate any of these products by using KMS or Active Directory, you must first download and install the Office LTSC 2021 Volume License Pack. This download contains an executable file that extracts and installs KMS host license files. These license files are required for the KMS host service to recognize KMS host keys for Office LTSC 2021, Project 2021, and Visio LTSC 2021. You can use the same KMS host key to set up Active Directory-based activation.
