Deploying Office LTSC License Using ODT and XML

LTSC Deployment Assistance as a Best Effort Support since it is Out of CSP Scope

Remove existing versions of Office before installing Office LTSC 2021

We recommend that you uninstall any previous versions of Office before installing Office LTSC 2021. To help you uninstall versions of Office that use Windows Installer (MSI) as the installation technology, you can use the Office Deployment Tool and specify the RemoveMSI element in your configuration.xml file.

There are several ways that you can use the RemoveMSI element when installing Office LTSC 2021.

• Uninstall all Office products on the device.
• Identify any existing language resources, like language packs, and install the same languages.
• Keep some Office products and uninstall all other Office products on the device.

RemoveMSI can be used to uninstall 2007, 2010, 2013, or 2016 versions of Office, Visio, or Project that were installed using Windows Installer (MSI).

For more information about using RemoveMSI, see Remove existing MSI versions of Office when upgrading to Microsoft 365 Apps. Even though this article is about Microsoft 365 Apps, most of the information also applies to Office LTSC 2021.

To uninstall 2019 versions of Office, Visio, or Project from the device, use the Remove element. You use the Remove element because 2019 versions of Office, Visio, and Project are installed by using Click-to-Run, not Windows Installer (MSI).

Create the XML File using config.office.com

We need to create an XML File according to the license purchased by visiting config.office.com

Download the Office LTSC 2021 installation files

Once you have a copy of the ODT and have created your configuration.xml file, you can download the Office LTSC 2021 installation files to your local network. To do that, open an elevated command prompt, go to the folder where you saved the ODT and the configuration.xml file, and type this command:

setup /download configuration.xml

If you have saved the configuration.xml file with a different name, use that name in the command.

It will look as if nothing is happening, but the download is happening in the background. Once the download is complete, you are returned to a command prompt.

Install Office LTSC 2021 by using the Office Deployment Tool

Once you have a copy of the ODT and have created your configuration.xml file (and downloaded the Office LTSC 2021 installation files to your local network, if necessary), you can install Office LTSC 2021. To do that, open an elevated command prompt, go to the folder where you saved the ODT and the configuration.xml file, and type the following command:

ConsoleCopy

 

setup /configure configuration.xml

If you have saved the configuration.xml file with a different name, use that name in the command.

Once the installation is complete, you are returned to a command prompt and you can go open the Office LTSC 2021 programs you’ve installed.

Note:

Office LTSC 2021 is installed on the system drive, which is usually the C:\ drive. The installation location can't be changed.
