Validation helps identify some common problems that may be encountered when attempting to upgrade an existing Windows Installer–based installation.
Note:You can perform upgrading and patching validation on uncompressed releases only.
The validation engine for upgrading and patching currently consists of different validators that are designed to test for a specific condition and report failure as necessary. Upgrading and patching validation was designed to facilitate the detection of upgrade scenario issues and is distinct from Windows Installer validation, which is better suited for validating first-time installation issues.
