Chapter 17: Updating Applications
Working with Upgrades and QuickPatch Projects
To create a QuickPatch project for an existing .msi file or an already existing QuickPatch, use the Create
New QuickPatch Wizard. Completing the wizard ensures that all basic requirements for the QuickPatch
project are met.
Creating a QuickPatch Project for an Existing QuickPatch
Project: This information applies to QuickPatch projects.
You can create a new QuickPatch project based on an existing QuickPatch project. This creates a patch
that you can deliver to any end users who need to apply a patch for the original application or specific
patched versions of the application.
Caution: If you open and modify any of the releases listed in the History of the General Information view, your latest
project will not work, since intermediate data shared across the releases in the History may have been lost or altered.
Therefore, whenever you create a QuickPatch project for an existing QuickPatch project, InstallShield changes the existing
QuickPatch project (.ise file) to read-only mode.
Task To create a QuickPatch project for an existing QuickPatch project:
1. In InstallShield, open the QuickPatch project (.ise file) that you would like to patch.
2. On the Tools menu, click Create QuickPatch.
Your new QuickPatch project opens in InstallShield.
You can also use the Create New QuickPatch Wizard to create a QuickPatch for an existing QuickPatch.
Specifying Whether to Streamline the QuickPatch Package
Project: This information applies to QuickPatch projects.
When you are configuring a QuickPatch project, you have the ability to specify whether you want
InstallShield to streamline the creation of your QuickPatch package to build as simple a package as
possible. The goal of QuickPatch streamlining is to generate a QuickPatch package that has fewer new
subfeatures and custom actions than a non-streamlined QuickPatch package.
For example, if your QuickPatch project includes a new file or registry entry and InstallShield does not
use QuickPatch streamlining, InstallShield creates a new subfeature for that file or registry entry.
InstallShield also adds one or more prebuilt InstallShield custom actions to work around certain
Windows Installer patch requirements. However, if InstallShield does use QuickPatch streamlining, the
file or registry entry is added to an existing feature, and no special prebuilt InstallShield custom actions
are required.
Note: InstallShield cannot streamline the creation of a QuickPatch package in the following scenarios:
