Make Office 2003 default open with 2007

[ea]

How can I make 2003 be the default open when you click on a .doc file. We
have 2003 and 2007 installed and it opens in 2007.

Thank you

I have to ask, is there a reason for keeping 2003, since 2007 can both open
& save plus create in the old format?

Yeap, Well, is a sharing computer ..and the oldman "the owner" uses 2003 and
for my school we use 2007, and he uses most of the time, he doesnot want to
know anything about 2007

Try this;

You should specify the default version of each application by
registering it using 'Start | Run'. If you don't register the
application then the last version installed becomes the default.

(Enter the full file path and name of the program, note that
/regserver is outside the quote marks.)
"C:\Program Files\Microsoft Office\Office11\Excel.exe" /regserver
The above will register Excel 2003 as the default on most systems -
change the file path / file name as appropriate.

The above was taken from an MS doc. - origonally pertaining to earlier
versions of Office, I'm assuming it is relevent to later versions
