Project: This information applies to Basic MSI projects.
For information on multiple-instance support for InstallScript projects, see Running an InstallScript Installation Multiple Times.
To create a patch that updates multiple instances of a product, begin by creating a minor upgrade or a small update. Then configure a patch in the Patch Design view. For the previous setup, select the Setup.exe file or the .msi file of the earlier installation that installs the version of the product that you want to upgrade. For the latest setup, select the Setup.exe file or the .msi file of upgrade release.
Tip: For detailed information about creating upgrades and patches, see Updating Applications.
At patch build time, InstallShield creates an Update.exe file or an .msp file, depending on how you have configured the patch in the Patch Design view.
For an overview on the run-time behavior of a patch that includes multiple-instance support, see Run-Time Behavior for Installing Multiple Instances of a Product.
