Microsoft Office XP is available as a non-upgrade version (full version) and as an upgrade version. The upgrade version requires that a qualifying product is installed on your computer or that the installation media from the qualifying product is available when you run the Setup program. The setup program for the upgrade version of Office XP attempts to detect qualifying software on the computer on which it is running. If the setup program is unable to detect a qualifying program on the computer (such as Office 97 or Office 2000), an error occurs.

If you do not have a valid qualifying product, return the Office XP Upgrade product, and purchase a full retail version of the Office XP product.
