                   Driver Installer/Uninstaller v3.4/3.4 Release Notes
                     Copyright (C) 2011 Silicon Laboratories, Inc.
		 --------------------------------------------------


This release contains the following components:

   * DriverInstaller.exe - Installation executable with embedded uninstaller. These executables
	are paired for installation of Silicon Labs driver sets. The uninstaller executable is
	embedded within the DriverInstaller.exe and are extracted during the driver installation
	to the installed directory (if it exists, if not it is copied to a standard Silicon
	Labs directory). The DriverInstaller.exe is driven by a setup.ini file which contains all
	the customization for the installation and install/uninstall modes.

   NOTE: This package contains the latest executable for use with a driver set. Simply drop in and
	replace the older installation EXE in your customized driver set. Rename the EXE file to your
	desired setup name, and it will be ready to run.
