Microsoft releases software updates in self-extracting file formats that automatically run a Setup program. This Setup program is included in the package. We do not support repackaging software updates that use the Update.exe package installer, or any other installer, into the Microsoft Windows Installer (.msi) package format. We only support installations of Microsoft software updates that use the installer that is included in the package that is supplied by Microsoft.
Repackaging is defined as converting an installer package from one package format, such as from the Update.exe package format or from the IExpress package format, to the Windows Installer package format. Microsoft software updates that use the Update.exe package format or that use other installers are not designed to run as repackaged Windows Installer files. If you apply a repackaged software update, you may experience unexpected results. For example, your application or you operating system may stop functioning.
Microsoft does not support repackaged software updates that customers repackage to use a different installer. Update.exe and Windows Installer are not interchangeable. Packages that are built by using one Installer technology have been tested and optimized to work only with that technology.
Windows Installer does not support some features that are required to apply Windows software updates:
Do not use the Update.msi package to deploy other software updates. Use the Update.msi package to deploy only the Windows service pack that it was released to deploy.
For more information about how to deploy Windows service packs, see the appropriate Service Pack Deployment Guide on Microsoft TechNet.
