Unfortunately, Office 2003 can not be "cross" upgraded. In other words, one
Office 2003 product can't be used as an upgrade qualifier for another Office
2003 product. You will need to find or purchase an older version of Office
to install your Office 2003 Pro upgrade. (Office 2007 is the first and only
Office product that can be cross upgraded.)
See this KB article
http://support.microsoft.com/kb/315995 and a portion is
reprinted below:
"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. "
