Adobe CS 4 will hangs at 80% of installation

Just hangs while "checking system profile"

Note:

(Point Zero's issue...DVD-ROM faulty. Ran Disk Utility simultaneously with installer and the installation went through fine.)

Mount the setup image, in my case it is Adobe Master CS4 (ADBESTAMCS4_LS5.dmg)

Open up terminal
Login as Super User
"sudo -s"
"*******"
Go into the Disk directory
"cd /Volumes/Adobe\ CS4\ Master\ Collection\"
Go Further
"cd Adobe\ CS4\ Master\ Collection\Setup.app\Contents\MacOS\"
Open the Installer
"open ./Setup"

And there you go!
