The uninstall program removes only items that the installation program
installed. If you add anything to a directory that was created by the
installation program, the uninstall program does not delete that directory,
because the directory is not empty after the uninstallation. You will need to
remove any remaining components yourself.
After the uninstall program completes, select OK, then restart your
computer.
If you want to reinstall the hardware and software, refer to the getting
started manual.
