I don't know the best answer to your question, but you might use the pasted info and see if you can find the gadget and delete. I have no idea how this might effect your system, so be careful. You might do a registry search prior to deleting it to see if the file is referenced there.
Maybe I misunderstood. Try using the Nero Clean tools to uninstall. I don't think anyone uses the control panel. http://www.nero.com/nero7/enu/Nero7_CleanTool.html
