InstallShield 2024

Project: This information applies to the following project types:

InstallScript MSI

A minor upgrade is a change to the product database and files large enough to merit a change to the ProductVersion property but not to the ProductCode property. In other words, both the package code and the product version number are different than those in the earlier installation package, but the product code of the minor upgrade does not change. An example is updating version 1.1 of a product to version 1.2. Minor upgrades usually do not have significant changes to the installation organization between versions. A minor upgrade packaged as a full installation acts like a first-time installation if an earlier version is not present, or it installs over an existing installation of a product. Essentially for an upgrade of an existing installation, a minor upgrade installs the differences between your version 1.2 and 1.1 application.

Note:During InstallScript MSI minor upgrade, if the base version of the product is installed to a location other than the default and new components are added to a subfolder of INSTALLDIR, the new component files are installed to the default location instead of the user-specified subfolder location.

For workaround, refer the InstallScript MSI Installs to Default Location During Minor Upgrades KB article.

Tip:You can modify the product version for your upgrade in the General Information view.
