connector of your computer.

be running?
Installation may not occur correctly if other programs are running. Be sure to close all
other programs before installing.
Are you attempting to install from a networked CD-ROM drive?
You cannot install from a networked CD-ROM drive.

If the CD-ROM or the lens of your CD-ROM drive are dirty, the installer may not work
correctly. Use a commercially available CD cleaner or lens cleaner to clean the CD-ROM
and/or lens.
Are the power conservation settings of your computer turned off?
If power conservation settings are turned on for your computer, disable these settings.
