excel 2010 open in separate windows

We are trying to open excel in separate windows for a user in excel 2010.  I did the registry edit trick for xls and xlsx files and .xls files will open in new windows, which is great.  However, when he tries to open .xlsx files, it is not working.  It opens a blank excel form.  Any ideas?

I have done that already.  The only thing that looks different is
"C:\Program Files\Microsoft Office\Office14\EXCEL.EXE" /e "%1"
on his computer it says
"C:\Program Files\Microsoft Office\Office14\EXCEL.EXE" /dde "%1"

It has /dde instead of just /e.  Anybody know what that stands for?
