MSI Validation, Warning/Error Sorting on Top

The MSI Validation feature checks the internal consistency of an MSI or MST. When validation finds many results, Master Packager places warnings and errors at the top of the list so you can review the most important items first.

Validation is an important step before testing or release because it helps catch issues that can affect installation, uninstallation, or runtime behavior.

How to use it

1. Open your MSI or MST in Master Packager.
2. On the Tables menu, select Validate, or press F5.
3. Review the results shown at the bottom of the window.
4. Resolve the warnings and errors that are sorted to the top before building or deploying the package.

Result fields

Field	Description
ICE code	Shows the ICE rule that reported the issue.
Type	Shows whether the result is a Warning or Error.
Description	Explains the reported issue.
Table, Column, and Primary Key	Show where the problem occurs in the database.

When to use it

Use this feature when you need to:

• Review many warnings or errors quickly.
• Check MSI or MST integrity before deployment.
• Troubleshoot complex installers with many components or dependencies.

tip

Run validation regularly during packaging so critical issues are easier to catch before testing or release.
