Having problems uninstalling Office 2010, 2007, or 2003 from the Control Panel? Use the Fix it Tool
To ensure that your Office 2010 installation works smoothly and efficiently, we recommend that before installing Office 2010, you uninstall any earlier versions of Office that may still reside on your computer. If you find that uninstalling these versions cannot be done effectively from the Control Panel, then use the Fix it tool. Be sure to use the Fix it Tool version that is designed for the particular Office suite (Office 2010 released/beta/trial versions, Office 2007, Office 2003) that you are uninstalling.
