I have windows xp home edition SP3. I installed Microsoft Office 2010 version without uninstalled office 2003 first. I can't uninstall Office 2010 now from Add/Remove programs. It did let me uninstall Office 2003, but when I try to reinstall Office 2003 my Outlook doesn't work at all. Any one have any ideas of how to unistall Office 2010 so I can get back to Office 2003 when all was working correctly. I have tried to do a system restore to prior to that date, but no luck. I may have to just reimage my Hard Drive and start over. Any help would be much appreciated.
