I have an XP machine on Fusion and Lion and the mac. Is it possible to set up Excel and Word on the Mac to be the default Excel and Word program that the XP machine uses. I have a few programs that need to have Excel and Word in order to export spreadsheets (Quickbooks and one other program). Right now I'm using an old version of Excel but it is pretty old and I have a newer version of them on the Mac. Is it possible to get Quickbooks and the other software to recognize this?
