Oracle 9i release 9.2. Installation problems

Hi,

I am experimenting with the above mentioned database and I would like to install additional components from the installation disks. Now when I start the installer all I see is something about already installed components and deinstall components. Where or how can on install the things initialy left out?

Thanx for your help.
