First go to this page where you can download the Open XML Converter for Macintosh. This program allows you to open Office 2008 programs in older versions of Microsoft office. It also includes all the fonts for Office 2008. So you can either run the installer and it will install itself, or if you are a bit uneasy about installing Microsoft products on your computer, right click on the installer and select show package contents. Open the folder called ‘Contents’ then ‘Packages’ then select ‘show package contents’ of the file that is called OpenXML_all_fonts. Open the folder called ‘Contents’ then double-click on ‘Archive.pax.gz’
Very useful!!!
