I just want to find out the best, safest, and most efficient way to install Office 2008 for the Mac when I currently have 2004 installed. Does the installer do an upgrade or does it install a separate version (2008) while retaining the old version (2004)? What if I have a lot of things I want to carry over from 2004 to 2008? Will it carry all of my Entourage mail, contacts, etc. and my preferences and customized toolbars for Word, Excel, Powerpoint or do I need to somehow import them after installation and/or recreate them? I have downloaded the most recent service pack 12.1, but need to do the basic installation of 2008 (updating or overriding my 2004 version). Thanks, Jim
