57 Installing and Using Application Programs
Installing applications from a CD-ROM disc
Sometimes you’ll install an application program on your internal hard disk
from a CD-ROM disc that contains the program. (For instructions on using a
CD-ROM disc, see “Inserting a CD-ROM Disc” and “Ejecting a CD-ROM
Disc” in Chapter 5.)
Follow these general guidelines when installing applications from a CD-ROM
disc and also check the disc itself for specific instructions:
m If there is a program Installer icon on the CD-ROM disc, double-click the
icon to install the program on your hard disk. When the installation
finishes, click the new version of the program’s icon on your hard disk to
open it.
m If instructions tell you to copy the disc’s application program to your hard
disk, do so by dragging the program’s icon to your hard disk. However, do
not follow any instructions on the CD-ROM disc to copy such items as
QuickTime, Sound Manager, or System Folder files to your hard disk. Your
computer already comes with the most up-to-date versions of these items,
which have been tested for compatibility with each other and all the other
software on your Macintosh. By replacing your hard disk’s items with the
versions on the CD-ROM, you may be installing outdated or incompatible
software, which could cause problems.
Note: You don’t have to copy or install a program every time you want to use
the program, only the first time. However, to use some interactive applications
that come on a CD-ROM disc, the disc must be in the CD-ROM drive and its
icon visible on your desktop, even if you have previously installed the
application on your hard disk.
