functions, see support.microsoft.com.
System Recovery On Failed Installation
The Microsoft Software Installer (MSI) provides the ability to return a system to its fully working condition after a failed
installation. MSI does this by maintaining an undo operation for every standard action it performs during an install, upgrade,
or uninstall. This operation includes restoration of deleted or overwritten files, registry keys, and other resources. Windows
temporarily saves all files that it deletes or overwrites during the course of an installation or removal, so that they can be
restored if necessary, which is a type of rollback. After a successful installation, Windows deletes all of the temporary backup
files.
In addition to the rollback of MSI Standard Actions, the library also has the ability to undo commands listed in the INI file for
each application if a rollback occurs. All files that are modified by the installation actions are restored to their original state if
a rollback occurs.
When the MSI engine is going through the installation sequence, it ignores all actions that are scheduled as rollback actions. If a
Custom Action, MSI Standard Action, or a installation action fails, then a rollback starts.
You cannot roll back an installation once it is completed; transacted installation is only intended as a safety net that protects the
system during an installation session. If you want to remove an installed application, you should uninstall that application.
NOTE:
Driver installation and removal is not executed as part of the installation transaction and therefore cannot be rolled
back if a fatal error occurs during execution.
NOTE: Installations, uninstallations, and upgrades that you cancel during installer cleanup, or after the installation
transaction is completed, are not rolled back.
Failed Updates
Apply the MSI patches and updates provided by vendors to the original vendor MSI packages provided. If you intentionally or
accidentally repackage an MSI package, or make changes to it directly, patches and updates may fail. MSI packages must not be
repackaged; doing so changes the feature structure and Globally Unique Identifier (GUID), which break any provided patches or
updates. To make any changes to a vendor-provided MSI package, use a .mst transform file.
NOTE:
A GUID is 128-bit long, and the algorithm used to generate a GUID guarantees unique GUID. The product GUID
uniquely identifies the application.
Upgrading Managed System Software
The Systems Management installer provides an Upgrade option for upgrading Server Administrator and other managed system
software.
The setup program runs the prerequisite checker, which uses the system's PCI bus to search for installed hardware, such as
controller cards.
The setup program installs or upgrades all of the managed system software features that are appropriate for the particular
system's hardware configuration.
NOTE: All user settings are preserved during upgrades.
