This version requires Excel 2007 to use. The last version supporting Excel 2003 is provided as an archived download here: January 11, 2012 Golf Stats Tracker (Excel 2003 or older). Note the Excel 2003 version is no longer updated and there are many differences from the current version so see the documentation included in the download for instructions on its use.
