Does Visio Desktop Support the Office Add-in Store? Troubleshooting & Guide
Question details
The user wants to know if Visio Desktop provides an integrated Office Add-in Store experience to browse and install add-ins.

- Product
- Microsoft Visio Desktop
- Device & OS
- Windows
- Scenario
- Attempting to find and install add-ins via the standard Office Store interface within the Visio Desktop application.
- Observed behavior
- The Office Add-in Store is missing or unsupported in Visio desktop applications, unlike in standard apps such as Word and Excel.
Ensure you have administrator privileges on your computer, as manually installing COM add-ins often requires system-level permissions.
Manually Install COM Add-ins for Visio
Since the integrated Office Store is not supported in Visio, you must obtain and manually install add-ins in the COM format directly from the developers.
Visio desktop applications, including Visio 2019 Professional, do not support standard Office Add-ins in the integrated store format. Instead, users must rely on COM add-ins.
The Microsoft Store on Windows is also not a supported distribution method for these add-ins. You will need to download the installation packages directly from verified third-party developers.
Obtain the COM add-in installation file (typically an .exe or .msi file) directly from the official website of the add-in developer.
Double-click the downloaded installation file and follow the specific deployment instructions provided by the developer to install the add-in onto your system.
Open Visio Desktop, click on 'File' > 'Options', and select 'Add-ins' from the left sidebar to confirm that the newly installed COM add-in appears in the active list.

Experience Built-in Diagramming with WPS Office
If you are tired of dealing with complex COM add-in installations and restricted store features, consider switching to WPS Office. It provides comprehensive document creation tools along with built-in flowchart and mind-mapping capabilities—no extra add-ins required.
- 1. Download WPS Office: Visit the official WPS Office website and click 'Download' to get the free installation package.
- 2. Install the Software: Run the setup file and follow the on-screen instructions to complete the fast, lightweight installation process.
- 3. Use Built-in Diagram Tools: Launch WPS Office, open a new document, and navigate to the 'Insert' tab to instantly access powerful flowchart and diagrammatic features.
