Like when you double click on them in windows explorer?

You could reregister excel.
close excel (all instances)

windows start button|Run
type:
"C:\your path to excel 2003\excel.exe" /unregserver
and hit enter.

Then in the Run dialog:
"C:\your path to excel 2003\excel.exe" /regserver

The /unregserver & /regserver stuff resets some of the windows registry to
excel's factory defaults.

And the last version of excel installed (or reregistered) will become the
default.
