Microsoft Office 2003 is available as a non-upgrade version (full version) and as an upgrade version. To install the upgrade version, one of the following requirements must be met:

• A valid qualifying product, such as Microsoft Office XP, Office 2000, or Office 97, is installed on your computer.
• The installation media of the valid, qualifying product is available.

When you run Office 2003 Setup, Setup tries to detect the qualifying product on the computer. If Setup cannot detect a qualifying program on the computer, Setup displays an error message. If you do not have a valid qualifying product, return the Office 2003 Upgrade product, and purchase a full retail version of the Office 2003 product.
