When overridden in a derived class, restores the pre-installation state of the computer.
Assembly: System.Configuration.Install (in System.Configuration.Install.dll)
The savedState parameter is null.
The saved-state IDictionary might have been corrupted.
An exception occurred during the phase of the installation. This exception is ignored and the rollback continues. However, the computer might not be fully reverted to its initial state after the rollback completes.
When you override the method in a derived class, be sure to call the base class's method first in your derived method. A rollback operation restores the computer to the state it was in before the installations occurred. The method is called if the Install method of this instance of Installer, or any installer in the installer collection, fail to run correctly. Any exceptions generated by calling the methods of the installers in the installer collection are ignored and the rollback of the other installers continues.
