Install or customize Office with the interface

  • Choose the language and the apps you need.
  • Choose the update channel.
  • Export the configuration to reuse it on other machines.

Understand activation and license features

The README lists online activation, phone activation, and KMS activation, along with license, key, and KMS management.

  • Confirm your license terms before activating.
  • Use the activation features only for licenses you are entitled to use.
