Powerpoint

I sometimes have to use powerpoint and have
just got a new Dell Insperation 1525 (v good by
the way) It has Vista and Basic Office 07,
which does not have power point or publisher I
have a disk with office 03 with both of these
on it, can I install them, obviously dont want
the word outlook etc that is also on there.

Appreciate this is a bit tight but I se them so rarely.

thanks Dave
