How to reinstall Office 2003, after Office 2010 uninstalled.(5 posts)

You will need to reinstall Office 2003.
"During installation process, if you select a default installation it WILL automatically uninstall 2003. You have to do a custom install AND tell it explicitly to NOT delete old applications"
