I never had a problem selecting all available options, not "Typical", and
letting the install program do its thing. Uninstall from Control Panel
(Add/Remove Programs). Put multiple versions into multiple folders; i.e,
Office1997, Office2000, Office2002, Office2003, etc. If you have trial
software, uninstall it first, then install your full licensed version.
Professional or Enterprise can upgrade Standard AFAIK.
