How to Fix Visio 2021 Installation Conflicts with Office LTSC 2021
Question details
The user needs to resolve an installation failure when deploying Visio Professional 2021 on a machine running Office LTSC Professional Plus 2021.
- Product
- Microsoft Visio 2021, Office LTSC 2021
- Device & OS
- not provided
- Scenario
- Attempting to install Visio Professional 2021 on a computer that already has or is simultaneously installing Office LTSC Professional Plus 2021.
- Observed behavior
- Visio Professional 2021 fails to install due to incompatible update channels, licensing types, or conflicting installation technologies.
Verify your current Office LTSC 2021 architecture (32-bit or 64-bit) and update channel before attempting to install Visio.
Align Deployment Configurations using the Office Deployment Tool
Ensure that both Visio 2021 and Office LTSC 2021 use compatible licenses, architectures, and update channels to prevent installation blocks.
Microsoft requires all Office products installed on the same computer to share the same installation technology (Click-to-Run) and use compatible update channels. Mixing different architectures or conflicting update channels will trigger an installation conflict.
Open an existing Office application like Microsoft Word. Click on 'File', select 'Account', and click 'About Word'. Note whether the installation is 32-bit or 64-bit. Your Visio installation must match this architecture.
In the same 'Account' menu under 'Product Information', check your Update Channel. Office LTSC 2021 typically uses the Perpetual Enterprise Channel. Ensure your Visio installation is configured to use this exact same channel.
Download the Microsoft Office Deployment Tool (ODT). Open your configuration XML file in a text editor and ensure that both Office LTSC 2021 and Visio 2021 are specified within the same configuration file, sharing identical Channel and Version attributes.
Open Command Prompt as an administrator. Navigate to the folder containing the ODT and run the command 'setup.exe /configure yourconfiguration.xml' to deploy both products simultaneously without conflict.

Frequently Asked Questions
Can I install a volume-licensed Visio with a retail version of Office?
Generally, this is not supported. Microsoft requires volume-licensed products like Visio LTSC 2021 to be installed alongside other volume-licensed Office products using the Click-to-Run technology.
Why am I getting a Click-to-Run and MSI conflict error?
Microsoft does not support installing an MSI (Windows Installer) version of Visio on the same computer as a Click-to-Run version of Office. Both applications must use the Click-to-Run deployment method.
Can I run 32-bit Visio with 64-bit Office LTSC?
No, all installed Office and Visio products on a single computer must share the identical architecture. You must install the 64-bit version of Visio if you are already running 64-bit Office LTSC.
Where can I find the official deployment guide for Visio LTSC 2021?
The official deployment guide is available on the Microsoft Learn website under the Microsoft 365 Apps deployment documentation, specifically detailing supported combinations for Office, Project, and Visio.
