Change Office Edition

This option is available in the main menu of MAS. You can use this script with Office C2R (Ver 16.0.9029.2167 and later) to change, add, and remove editions or change the current Office update channel.

How does it work?​

Office C2R (Click To Run) has a unified installation system, meaning that whether you download a single app like Word 2021 or a full package like ProPlus2021, the core files installed are nearly identical.

The main management program for Office C2R is located at C:\Program Files\Common Files\microsoft shared\ClickToRun\OfficeClickToRun.exe

The script leverages this program to add, remove, or change Office editions. Because of Office's unified installation and delta updates, adding new editions or apps does not require a large download.

Change Office update channel​

This script can also change the current Office update channel.

VL (LTSC) channel limitations​

(Applicable to 2019/21/24 VL)

Officially, the update channel can not be changed to or from a VL (LTSC) channel, so if the installed channel is a VL (LTSC) channel, only that channel will appear in the script.
Also, if the installed channel is not an LTSC channel, the script won't offer to change to LTSC.

Windows 7/8/8.1 limitations​

Office C2R is no longer supported on Windows 7, 8, and 8.1.
The last available build is fixed and won't get any updates. VL (LTSC) channels are not supported on these Windows versions so they won't appear in the script.
