Rolls back service application information written to the registry by the installation procedure. This method is meant to be used by installation tools, which process the appropriate methods automatically.
Assembly: System.ServiceProcess (in System.ServiceProcess.dll)
Normally, you will not call the methods on ServiceInstaller within your code; they are generally called only by the install utility. The install utility automatically calls the Install method during the installation process. It backs out failures, if necessary, by calling on the object that generated the exception.
An application's install routine maintains information automatically about the components already installed, using the project installer's Installer.Context. This state information, passed into as the savedState parameter, is continuously updated as the ServiceProcessInstaller instance and each ServiceInstaller instance is installed by the utility. It is usually unnecessary for your code to modify this state information explicitly.
