I HAD AN AUTOMATED MESSAGE ON THE COMPUTER TELLING ME THAT MY TRIAL VERSION OF OFFICE 2003 HAD EXPIRED AND SAID TO CLICK HERE TO REGISTER AND HERE TO DELETE. I CLICKED THE DELETE BUTTON AND NOW HAVE "WINDOWS INSTALLER" POP UP EVERY TIME I OPEN A WINDOW, PROGRAM, EMAIL, ANYTHING AND THEN SAYS "PREPARING TO INSTALL". THEN I HAVE TO WAIT ABOUT 2 MINUTES, MAYBE MORE FOR THAT POPUP TO DISAPPEAR. HOW DO I MAKE THIS PROBLEM GO AWAY?????????????????? THANKS IN ADVANCE
