How to Install Project and Visio 2021 LTSC with Microsoft 365 Apps
Question details
The user needs to install Project Standard 2021 LTSC, Visio Standard 2021 LTSC, and Microsoft 365 Apps on the same computer without one uninstalling the other.
- Product
- Microsoft 365 Apps, Project 2021 LTSC, Visio 2021 LTSC
- Device & OS
- not provided
- Scenario
- Deploying multiple Microsoft Office applications with different licenses on the same workstation.
- Observed behavior
- Installing the products together causes one product to automatically uninstall the other due to incompatible update channels or versions.
Ensure you have administrative privileges on your computer and have backed up any existing Office configuration files or product keys.
Use the Office Deployment Tool to Match Update Channels
Configure your installation so all products share the exact same update channel and version to prevent conflicts.
Microsoft Office products installed on the same computer must use compatible underlying update channels. Mismatched channels will force the installer to remove conflicting applications.
Visit the Microsoft Download Center, download the Office Deployment Tool (ODT), and extract its contents to a new folder on your computer.
Use the web-based Office Customization Tool or a text editor to create a configuration.xml file. Ensure that the 'Channel' attribute is identical for Microsoft 365 Apps, Project 2021 LTSC, and Visio 2021 LTSC.
Open Command Prompt as an administrator, navigate to the folder where you extracted the ODT, and type 'setup.exe /configure configuration.xml' to start the installation.
Perform a Windows Clean Boot
If matching the update channels does not resolve the conflict, perform a clean boot to prevent background services from interfering with the installation.
Avoid Installation Conflicts with WPS Office
If complex deployment tools and update channel conflicts are slowing down your workflow, consider switching to WPS Office. It provides an all-in-one, unified suite that installs quickly without any configuration headaches.
- 1. Download WPS Office: Visit the official WPS website and click the free download button.
- 2. Run the Installer: Open the downloaded file and follow the straightforward on-screen instructions.
- 3. Open Your Documents: Launch WPS Office and instantly open your existing documents, spreadsheets, and presentations.
Frequently Asked Questions
Why does installing Project 2021 LTSC automatically remove Microsoft 365 Apps?
This occurs because the Microsoft installer detects a conflict in the update channels or installation technologies (such as Click-to-Run). To coexist, both products must be configured to use compatible update channels during installation.
Can I install volume-licensed Visio 2021 with retail Microsoft 365 Apps?
Yes, but you cannot use the standard click-to-run installer directly. You must use the Office Deployment Tool to configure both installations to share the same update channel.
What is the Office Customization Tool?
The Office Customization Tool is a web-based interface provided by Microsoft. It helps administrators visually generate the necessary configuration.xml file required by the Office Deployment Tool, ensuring product IDs and update channels are correctly formatted.
