How to prevent RzPowerTool from requesting an update every single time I open my computer?

Every single time I boot up my computer, RzPowerTool requests an update. About half the time I allow it to update (I am the device administrator), but still it requests an update the next time I turn on my computer. Is this normal behavior? How can I prevent this from happening? Is there any way to disable automatic updates (various forums indicate there used to be a second settings menu with this option, but that no longer seems to be the case).
