Msispy: A Tool to Display Component-Level View of System

Msispy is an utility which comes along with Windows installer SDK. If you want to troubleshoot a MSI package in component level or feature level, I will recommend this tool as the best option for repackagers.It provides a nice GUI and command line utilities which makes it very user friendly.

MsiSpy provides a component level view of the products and features installed on a system, using either an MSI Package, or the registry information. Msispy also displays the status of each, and allows you to partially or completely re-install missing or damaged items.
