Thank you very much. Just to clarify - this would mean that I would have
2003 and 2007 installed on the same computer and could use one or the other
depending on my needs (anything I do for work would have to be 2003).
Yes, but unless you modify the shortcuts, prior to installing later version,
eg Word to Word03, they will be overwritten.
Also opening a file from explorer will result in latest version opening.
