If you want your minor-upgrade patch to essentially remove all of the patches up to the release to manufacturing (RTM) version of the product (or the most recent major upgrade of the product, if one has been installed) before applying the current minor-upgrade patch, select Yes for this property. With this option, all patches (with or without sequencing data) are removed. You do not need to target additional baseline versions and thus increase the patch payload. All end users can successfully apply the patch without applying any intermediate patches.

If you do not want your minor-upgrade patch to remove all of those earlier patches, select No. If you select this option, it may be necessary for your patch to contain the information needed to target each of the earlier minor upgrades that were created after the RTM (or the most recent major upgrade of the product, if one was created).

For example, if you are creating a minor-upgrade patch for service pack 2 and you select No for this property, your patch needs to target the minor-upgrade patch for service pack 1. You could also optionally target other baselines (such as RTM); doing so would increase the patch payload. Note that if you do not target the RTM version, any end user who has the RTM version but not the service pack 1 minor-upgrade patch would need to install service pack 1 before service pack 2.

Versions of Windows Installer earlier than 3.1 ignore this setting.
