I cannot open Firefox so decided to try and uninstall and reinstall, when the uninstall or install wizard starts I keep getting "Firefox must be closed to proceed, please close Firefox to continue" but i do not have Firefox open at all.

Originally I was having a problem with Firefox locking up everytime I went to a website and tried to X out of it, there would be no response. Or the little box would come up with the question on whether i wanted to Quit or close tabs, I would make my choice but nothing would happen. Then yesterday I couldnt open Firefox at all, so I tried to uninstall and also reinstall but keep getting the error message "Firefox must be closed to proceed, please close Firefox" But i do not have it running anywhere, it does show in my downloaded programes, but I cant do anything with it. I am running Windows 7 on a Dell Inspiron
