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

There is no upgrade support to Server Administrator 9.3.2 from the previous version. You must uninstall the previous version, and then

install Server Administrator 9.3.2.

Upgrading Guidelines

• You can upgrade to the latest version of Server Administrator from any of the previous three versions. For example, upgrade to Server

Administrator 7.3 is supported only for Server Administrator versions 7.0 and later.

• You can upgrade to the latest version of Server Administrator which includes Linux granular installation. If you require the Linux

granular installation options, you must uninstall the existing version of Server Administrator and install the latest version of Server

Administrator. .

• To upgrade from versions earlier than 6.3, uninstall the existing version of Server Administrator and reinstall the latest version of

Server Administrator.

• When upgrading an operating system to a major version, uninstall the existing Systems Management software and reinstall the latest

Systems Management software. When upgrading only to an update level change (for example, Red Hat Enterprise Linux 5 Update 7 to

Red Hat Enterprise Linux 5 Update 8), upgrade to the latest Systems Management software; all user settings are preserved.

NOTE:

Uninstalling Systems Management software deletes its user settings. Reinstall Systems Management

software and apply the user settings.

• If you have installed Server Administrator Web Server version 7.3, ensure that you install Server Instrumentation version 7.3 on the

managed system. Accessing an earlier version of Server Administrator using Server Administrator Web Server version 7.3 may display

an error.
