I have forgotten how to do this - someone will tell you soon. I think you
use /unreg and /reg in two Run path\excel.excel.exe commands.

BUT be aware that after opening one version of Word, when you go to open the
other (at any time) there will be a looooong wait. This is not the case with
Excel.
best wishes

Hello,

I have installed the 60 days trial version of 2007 to run alongside 2003
on
a client's PC.

If she double clicks on an Excel file (Word also) I would like it to
automatically open in the 2003 version. I only want 2007 to open if she
purposely chooses it from the Start menu.

Thanks in advance
Judith
