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 any files that it deletes
or overwrites during the course of an installation or removal, so they can be restored if necessary, which is
a type of rollback. After a successful installation finishes, Windows deletes all of the temporary
backup files.
In addition to the rollback of MSI Standard Actions, the Dell OpenManage 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 Dell OpenManage installation actions will be 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 Dell OpenManage installation action
fails, then a rollback starts.
An installation cannot be rolled back once it has finished; 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, for instance, you should simply 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 complete, will not be rolled back.
