them during installation. Do not drag them to your hard disk.
If you’re installing software from a CD: Start up your computer from the CD,
and then open the System Software Installers folder. (For instructions on
starting up your computer from a CD, see the manual that came with your
computer or CD-ROM drive.)
If you’re installing software over a network: Find the Installer on your file
server. If you’re not sure where it is, ask your network administrator.
