Sure, but you have to uninstall any trial first, clear temp files & reboot,
prior to installing from CD.
Assuming you didnt do this, uninstall all versions of MS Office, including
any activation wizard,then reboot.
Then assuming all versions of Office have been removed - check first! - if
they havent theres other steps to follow.
Then install Office 2003 from your cd (I assume its a retail version, not
one supplied when you purchased your old PC)
*Before* you start Outllook how did you transfer your old pst, and where did
you place it?
