ICE Validation

The ICE Validation feature helps identify structural and logical issues in an MSI by running Microsoft's Internal Consistency Evaluators (ICE).

By default, Master Packager uses the official Microsoft darice.cub validation file, but you can also load additional .cub files and choose the ones you want to use.

What validation shows

• Warnings and errors.
• Details about each issue and possible corrections.
• Severity levels for faster review.

How to run it

1. Open the MSI or MST in Master Packager.
2. Start validation from the validation window, or press F5.
3. Review the reported issues and correct them before deployment.
