How to Install Office 2021 Pro LTSC and Visio 2021 Pro LTSC
Question details
The user needs to install Office 2021 Professional Plus LTSC and Visio 2021 Professional LTSC locally without relying on the Microsoft 365 admin center for deployment.
- Product
- Microsoft Office 2021 LTSC, Visio 2021 LTSC
- Device & OS
- not provided
- Scenario
- Deploying volume-licensed LTSC versions of Office and Visio using configuration files instead of traditional executable installers.
- Observed behavior
- The user requires the correct deployment method and tools to bypass the Microsoft 365 admin center and successfully install the software.
Ensure you have administrator privileges on your computer and have downloaded the latest version of the Office Deployment Tool (ODT) from the Microsoft Download Center.
Use the Office Customization Tool and Office Deployment Tool
Generate a custom configuration file using the web-based Office Customization Tool, then execute it locally with the Office Deployment Tool to install the software.
Unlike standard consumer versions of Office, LTSC (Long Term Servicing Channel) products do not provide a standalone executable installer. They strictly require the Office Deployment Tool (ODT) to interpret an XML configuration file, download the necessary installation files, and deploy the software.
Navigate to the Microsoft Office Customization Tool (config.office.com) in your web browser. Under the 'Products' section, select 'Office LTSC Professional Plus 2021' and 'Visio LTSC Professional 2021' from the respective dropdown menus.
Configure your language, installation settings, and update preferences. Once finished, click 'Export' at the top right to download your custom configuration file. Name it 'configuration.xml' and save it to a dedicated folder on your computer.
Run the downloaded Office Deployment Tool installer (setup.exe) and extract its contents directly into the same folder where you saved the configuration.xml file.
Open the Command Prompt as an Administrator. Use the 'cd' command to navigate to the folder containing your ODT files. Type the command 'setup.exe /configure configuration.xml' and press Enter to begin the installation.
Looking for a simpler alternative to Office 2021 LTSC?
Skip the complex XML configurations and command-line deployment tools. WPS Office provides a powerful, free, and highly compatible alternative that installs instantly with a standard installer, saving you time and IT resources.
- 1. Download the software: Visit the official WPS Office website and click the free download button.
- 2. Run the installer: Open the downloaded executable file and follow the straightforward setup wizard.
- 3. Start working instantly: Launch WPS Office and immediately begin creating or editing your documents without requiring license activation steps.
Frequently Asked Questions
Can I install Office 2021 LTSC without the Office Deployment Tool?
No. Microsoft requires the Office Deployment Tool (ODT) to install all volume-licensed versions of Office 2021 LTSC and Visio 2021 LTSC. Standard MSI installers are no longer provided for these versions.
How do I activate my Office and Visio LTSC products?
Activation is usually configured during the setup process. You can input your KMS (Key Management Service) or MAK (Multiple Activation Key) directly into the Office Customization Tool before exporting your XML file.
Can I install Visio LTSC 2021 on a machine that already has Microsoft 365?
Yes, but you must ensure that the installation technologies and update channels are compatible. Both must use Click-to-Run technology, and you generally cannot mix volume-licensed LTSC products with subscription products on differing update channels without specific XML configurations.
