These license files allow your KMS host service to recognize KMS Host keys for Office, Project, and Visio. The installer contains new KMS host license files.

In this article, we will discuss the basics of MS Office KMS activation (this guide applies to the volume editions of Office 2021, 2019, and 2016, including Project and Visio). You'll also need to install the Office Volume License Pack for each version of Office on the KMS host computer and activate a KMS host key for each version of Office. In these cases, the KMS host computer must be running an operating system that supports KMS for each of the versions of Office that you want to activate. You can also configure a KMS host computer to activate multiple versions of Office, such as Office LTSC 2021, Office 2019, and Office 2016. If you have a KMS host computer configured to activate Windows, you can configure that same KMS host computer to activate Office.
