It seems this is a difficult task because there doesn't seem to be answers: I have Logitech wireless keyboard & mouse (duo navigator) and have had it 3 years. I want to uninstall them completely and install a wireless MS keyboard and mouse, but I get this error message when I try to uninstall them in add/remove: "Sorry this software is not compatible with your operating system. Your device will still provide basic functionality. The installer will now close." I want it removed and I don't want to reformat the hard drive. I know it is difficult to remove completely (like Norton was) but if I could have some steps on how do it, I sure would appreciate any help I can get to take this stubborn program out. I have xp sp3.
