Allows you to build your QuickPatch package with an existing UpgradedImage folder. To use this option, you must have built this package at least once (so an UpgradedImage folder exists). Setting this option to No builds the package from the existing UpgradedImage folder. This allows you to tweak the MSI package in the UpgradedImage folder, and use that MSI data in a QuickPatch project. Setting this option to Yes (the default setting) regenerates the MSI file in the UpgradedImage folder every time the package is built.
