The Microsoft® Windows® Installer (MSI) is the application installation and configuration service for Windows. Version 4.5 of the Windows Installer has several new features, including:
Multiple Package Transaction: In a multiple package transaction, you can create a single transaction from multiple packages. In a multiple package transaction, a chainer is used to dynamically include packages in the transaction. If any of the packages do not install as expected, you can roll back the installation.
Embedded UI Handler: You can embed a custom user interface (UI) handler in the Windows Installer package. This makes a custom UI easier to integrate. You can also invoke an embedded UI handler from the Add or Remove item in Control Panel. Or, you can invoke an embedded UI handler during a Windows Installer repair process.
Embedded Chainer: You can use the embedded chainer to add packages to a multiple package transaction. You can use an embedded chainer to enable installation events across multiple packages. For example, you can enable the install-on-demand events, the repair events, and the uninstall events across multiple packages.
Update Supersedence Resiliency: This feature enables you to correct for changes in the FeatureComponent table during supersedence.
Shared Component Patching Resiliency During Uninstall: This feature makes sure that the most recent version of a component is available to all the products.
Custom Action Execution On Update Uninstall: This feature enables an update to add or change a custom action so that the custom action is called when an update is uninstalled.
After installation of this package, the version of Windows Installer on the system will be upgraded to 4.5.
