Hi, Please follow my advice...
click Start button (lower-left corner of monitor's screen).
click Control panel.
look "Add or remove programs" icon and click that.
wait for a minitue until the end of building list of installed programs...
search headline of "MS fix it..." in program list.
click "remove" button.
And you will see the uninstall dialog box.
follow the command or guides in that box.
bye.
