FAQ About Office Deployment Tool 2021
You can download Office LTSC 2021 Professional Plus using the Microsoft Office Deployment Tool. Download and extract the latest Office Deployment Tool, create a configuration.xml file for Office LTSC 2021, and then run the download command from Command Prompt as an administrator.
The Office Deployment Tool 2021, also known as ODT 2021, is a Microsoft command-line utility used to download, install and configure Click-to-Run versions of Microsoft Office. It allows you to choose the Office edition, language, architecture, update channel and applications you want to install.
Open Command Prompt as an administrator, navigate to the folder containing setup.exe and your XML file, and run:
setup.exe /download configuration.xml. The Office Deployment Tool will read the settings in the XML file and download the required Office LTSC 2021 installation files.
Use ProPlus2021Volume as the product ID when configuring Office LTSC Professional Plus 2021 in the Office Deployment Tool XML file.
Use PerpetualVL2021 as the update channel for Office LTSC Professional Plus 2021 and Office LTSC Standard 2021. Using an incorrect channel may prevent Office from downloading or installing correctly.
Microsoft generally recommends the 64-bit version of Office for computers with at least 4 GB of memory. However, the 32-bit version may be more suitable if you rely on older Office add-ins, macros or applications that are not compatible with 64-bit Office.
No. You cannot have 32-bit and 64-bit Office products installed together on the same device. Existing Office applications may need to be removed before installing a version with a different architecture.
Yes. Add the ExcludeApp element to your configuration.xml file to prevent specific applications from being installed. For example, you can exclude Access, Publisher, Outlook, OneDrive or other applications that are not required.
The Office Deployment Tool can remove older MSI-based Office installations when the RemoveMSI element is included in the configuration file. Existing Click-to-Run versions may require separate removal or additional XML settings before installation.
Common causes include an incorrect product ID, the wrong update channel, invalid XML formatting, insufficient administrator permissions, conflicting Office installations or an interrupted internet connection. Confirm that the XML uses ProPlus2021Volume and PerpetualVL2021, then run Command Prompt as an administrator.
After installation, open an Office application and enter your valid Office LTSC 2021 product key when prompted. Volume-licensed installations may be activated using a Multiple Activation Key, Key Management Service or Active Directory-based activation, depending on the licence provided by your organisation.

Yes. Office LTSC 2021 receives security, stability and quality updates, generally through the PerpetualVL2021 update channel. However, it does not receive new Office features after release.
Yes. You can reinstall Office LTSC 2021 using the Office Deployment Tool and your configuration.xml file. You will also need a valid product key and may need to reactivate Office after reinstalling it.
