QuickPatch Projects
Project: You can create a QuickPatch to update an earlier version of your product if the installation for the earlier version
was created with either of the following project types:
• Express
• QuickPatch
A QuickPatch project is a specific type of project recommended for installation authors who want to ship
small, single updates to their users. Changes that are more extensive such as adding custom actions and
changing .ini data typically require a standard patch.
QuickPatch authoring provides a simple alternative to creating a standard patch (which is available in
InstallShield Premier Edition and InstallShield Professional Edition), even though it provides less
customization. Fundamentally, both patch creation methods produce the same deliverable types: .msp
and .exe files.
With a QuickPatch, you can do any of the following:
• Add new files to the original installation or an earlier QuickPatch.
• Delete files in the original installation.
• Delete files that were added with an earlier QuickPatch.
• Perform the same set of above operations on registry entries.
• Remove custom actions that were included with the original installation but that do not apply to the
current QuickPatch project.
The creation of a QuickPatch project always begins with the Create New QuickPatch Wizard. Completing
the wizard ensures that all basic requirements for the QuickPatch project are met. Then you can
configure project settings once the QuickPatch project opens in InstallShield.
