- Scenario
- Creating a Database Model Diagram in Microsoft Visio.
- Observed behavior
- The Entity Relationship stencil is completely missing from the template, and basic installation repairs may not immediately resolve the issue if the software build is outdated.
Ensure you have an active internet connection and administrative privileges on your computer, as you may need to download updates and run system-level repairs.
Update Visio and Perform an Online Repair
Updating to the latest build and running a comprehensive Online Repair can fix corrupted stencils and missing templates.
Microsoft Visio versions like 2016, 2019, 2021, and Plan 2 share the same code base. When stencils fail to load, verifying your version and performing a deep system repair is the most effective way to restore missing components.
Open Visio, go to File > Account > Product Information, and verify your version number. Click 'Update Options' and select 'Update Now' to install any pending updates.
Create a new Database Model Diagram to check if the stencil appears. This helps determine if the issue is isolated to a single corrupted file.
Close Visio. Open the Windows Control Panel, navigate to Programs and Features, select Microsoft Visio from the list of installed applications, and click 'Change'.
Select 'Online Repair' (do not choose Quick Repair) and click 'Repair'. Follow the on-screen prompts to thoroughly fix the installation and redownload missing stencil files.

Manually Open the Missing Stencil
If the stencil files are still on your system but not loading automatically with the template, you can attempt to open them manually.
