Additional information about the VL Serializer

  • The VL Serializer provides native support for both Apple Silicon and Intel-based Macs.
  • The volume license is located in the /Library/Preferences/com.microsoft.office.licensingV2.plist file.
  • The licensing plist generated by the VL Serializer contains data that's encrypted by using the serial number of the boot drive on the device where it was generated. Upon each Office application launch, the plist is decrypted by using the current boot drive serial number as the decryption key. If the data can't be decrypted (for example, boot drive serial number is different), Office goes into an unlicensed state without warning.
  • Because the license plist file is encrypted using information from the device it's installed, you can't copy it to a different device to activate Office on that device.
  • There's a single VL Serializer package that contains a single key. That key is shared between all volume licensed customer installations.
  • The VL Serializer package contains a binary executable named "Microsoft Office Setup Assistant." It's this executable that actually activates the volume license.
  • The VL Serializer package is compatible with mobile device management (MDM) servers, such as Jamf Pro or FileWave.
