Running windows 7 and have a problem with Microsoft mouse and keyboard program keeps saying there is a fault with it, part of the file missing or damaged. Solution from Msoft is to reinstall the program but when I try it says “program already installed remove program to reinstall” but when I try and remove/uninstall the old program get message “can’t uninstall as program file missing or damaged” Catch 22. 
Is there a way of removing the old program?
