Just received a crop of updates for my XP laptop also running office 2003 and noticed one is for office 2007. I do have 2007 on my Vista PC and so have installed on my laptop the compatibility update to read .docx files in 2003. I've checked the link to Microsoft's information site but it doesn't help me understand if I need this update
Thanks Graphicool1 but that's the web page I refer to above. You'll notice it says "Applies to" then lists all flavours of Office 2007. It is that which makes me wonder why it was offered to my XP PC which runs Office 2003.
The only tenuous link could be, if it also applied to the compatibility pack which allows 2003 to read and save 2007 .docx files, though I would have thought it would have been mentioned.
