About Table Editor

The Table Editor lets you view and edit Windows Installer database tables directly in Master Packager. Use it when you need low-level control that is not available in the graphical editors.

The Table Editor is especially useful for advanced packaging, troubleshooting, and precise changes to table data and relationships.

note

Editing tables directly can break an MSI if the changes are incorrect. Back up the package before you modify table data or schema.

When to use it​

Use the Table Editor when you need to:

  • Modify tables that are not exposed through graphical views.
  • Troubleshoot installation issues related to table data.
  • Add or remove rows in tables such as CustomAction, FeatureComponents, Registry, or File.
  • Fine-tune values that require more precision than the graphical UI provides.
  • Trace relationships between tables.
