The system I need to put the software on actually requires Word 2003 and Excel 2003 (Believe it or not).  However, when I use the Volume License media kits to install the software, I am getting a message that the product key is invalid.  It was my understanding that you could use the serial # from a newer version on an older installation.  According to Microsoft downgrade rights chart, I should be able to use this 2010 license on a 2003 install.  Can anyone help or shed some light on this for me?

Office Productivity refers both to the act of being productive and efficient in an office or professional environment, as well as the software applications used to "produce" information. This includes the development of professional skills, creating work processes, and almost any program used to create or modify a document, image, audio or video clip. However, business application suites such as Microsoft Office, which include word processing, spreadsheet and presentation programs, are typically called productivity software, as contrasted with a "utility program," such as a file manager, which is used to organize files and folders on the computer. Many office- and business-oriented groups of programs are organized into suites.

Microsoft Word is a commercial document editing program that is part of the Microsoft Office suite. It features numerous text-editing tools for creating richly formatted documents, along with tools for the use of macros in Word documents. Word's native file formats are denoted either by a .doc or .docx file extension. Plugins permitting the Windows versions of Word to read and write formats it does not natively support, such as the OpenDocument format (ODF) are available. Word can import and display images in common bitmap formats such as JPG and GIF. It can also be used to create and display simple line-art.

Microsoft Excel topics include formulas, formatting, VBA macros and user-defined functions, and everything else related to the spreadsheet user interface, including error messages.
