Specify whether you want to use patch sequencing for your QuickPatch. A patch sequence accounts for obsolete patches, superseded patches, and patches that have already been applied to the product. The sequence specifies the order that Windows Installer 3.0 and later should apply patches to an installed product, regardless of the order in which they are provided to the target machine. For versions of Windows Installer earlier than version 3.0, the patch sequence is ignored, and any patches are applied to the product in the order that they are provided to the target machine.
