Fix Visio 2021 LTSC Cannot Install Alongside Office 2013
Question details
The user is unable to install Visio 2021 LTSC on a device that already has Microsoft Office 2013 installed due to conflicting installation technologies.
- Product
- Visio 2021 LTSC, Office 2013
- Device & OS
- not provided
- Scenario
- Attempting to deploy or install Visio 2021 LTSC Standard on a system running an existing Microsoft Office 2013 installation.
- Observed behavior
- The installation fails and displays an update-channel error because Visio 2021 LTSC uses the Click-to-Run deployment method (PerpetualVL2021), which is strictly incompatible with the MSI installation technology used by Office 2013.
Before proceeding, confirm that you have the administrative rights to uninstall applications, and ensure you have backed up any necessary Outlook PST files or unsaved Office 2013 documents.
Uninstall Office 2013 to Allow Visio 2021 LTSC Installation
Because MSI and Click-to-Run installation technologies cannot coexist on the same computer, you must completely remove the older Office 2013 MSI installation before installing Visio 2021 LTSC.
Microsoft enforces a strict compatibility rule that prevents Windows Installer (MSI) products and Click-to-Run products from being installed together if they share overlapping core components. To use your new Visio 2021 LTSC software, the older MSI suite must be removed.
Click the Windows Start menu, type 'Control Panel' into the search bar, and press Enter.
Click on 'Uninstall a program' located under the Programs category.
Locate Microsoft Office 2013 in the list of installed applications. Right-click on it and select 'Uninstall'. Follow the on-screen prompts to complete the removal process.
Once the uninstallation is complete, restart your PC to ensure all residual MSI registry keys and files are cleared from the system.
Run the Visio 2021 LTSC Click-to-Run installer. The installation should now proceed without the update-channel compatibility error.
Upgrade Office to a Click-to-Run Version
If you still require core Office applications (Word, Excel, PowerPoint) alongside Visio, you will need to replace Office 2013 with a newer, Click-to-Run version of Microsoft Office.
Need a Reliable Office Suite After Removing Office 2013? Try WPS Office
If uninstalling Office 2013 to accommodate Visio leaves you without essential word processing, spreadsheet, or presentation software, WPS Office is the perfect solution. It installs safely alongside specialized Microsoft tools without triggering Click-to-Run conflicts, while maintaining full document compatibility.
- 1. Download the Installer: Visit the official WPS website and download the free WPS Office installation file.
- 2. Run the Installation: Launch the executable file. WPS Office installs independently in a lightweight package, completely avoiding Microsoft's MSI or Click-to-Run registry restrictions.
- 3. Set Default Programs: Open WPS Office and set it as your default application to handle standard Office formats, allowing you to seamlessly edit documents alongside using Visio.
Frequently Asked Questions
Why are MSI and Click-to-Run installations incompatible?
Microsoft designed Windows Installer (MSI) and Click-to-Run as two distinct software deployment methods. They handle registry keys, shared application files, and system updates differently. Mixing them on the same system, especially across different versions, causes fatal registry conflicts, which is why Microsoft hard-blocks these installations from coexisting.
Can I convert my Office 2013 MSI installation to Click-to-Run?
No, Office 2013 volume licenses are structurally built on the MSI format. It is not possible to natively convert an existing MSI-based Office 2013 installation into a Click-to-Run format. You would need to upgrade to a newer version of Office that supports Click-to-Run deployment.
Is there any workaround to keep both programs on the same computer?
There is no direct workaround to install them on the exact same host operating system environment. The only practical workaround to keep both is to install one of the applications inside a virtual machine (VM) running a separate Windows instance.
What is the PerpetualVL2021 channel?
The PerpetualVL2021 channel is the specific Click-to-Run update channel assigned by Microsoft for Long Term Servicing Channel (LTSC) products like Office 2021 LTSC and Visio 2021 LTSC. It ensures that the software receives critical security updates without pushing major feature changes.
