Can't uninstall Safety MInder or Norton Online

I go to Program and Features in the control panel. I find Norton Safety Minder (v 2.3.0.18) and click the Uninstall/Change button, but absolutely nothing happens. I click Norton Online (v 2.3.0.7) and a dialogue comes up saying I need password to uninstall, but there is no place to put it, and the continue button doesn't work. I need to uninstall this to use the Norton removal tool to remove my Norton 360 to replace with new Norton Internet Security. Solutions?
