Upgrading InstallShield 11.5 or Earlier QuickPatch Projects that Have InstallScript Custom Actions

InstallShield 2016

QuickPatch projects that are created in InstallShield 12 and later for InstallScript MSI projects can only patch media that were also created with InstallShield 12 and later. If you want to use InstallShield 2016 to create an update for an application whose previous InstallScript MSI installation was created with InstallShield 11.5 or earlier, you should create a create a minor-upgrade package instead of a QuickPatch, and use the Patch Design view to create a standard patch. Subsequent patches from this version can be created as QuickPatch projects.

Creating a QuickPatch for a Basic MSI project (with or without InstallScript custom actions) has not been known to cause any issues.
