You should remove Office 2007 and all previous office versions. Then restart your system, and run a registry cleaner program. There are many program to clean the registry -- some free ones too. Be careful -- there are some that say they are free on the net but they are actually malicious software. After your run the registry clean, restart your system again, and then reinstall Office 2007. Make sure that the Office 2007 is the original CD or DVD.
