Unable to install CS4 Design Premium

[Gast]

Hi! I am trying to install CS4 Design Premium Student Edition on my second work computer.
It is a Windows Vista Home Premium, Service Pack 2, 32-bit Operating System. (As far as I know, all the system requirements are met?)

Initially I tried installing using the CDs, but it kept asking me to insert CD1, when I already have the Application 1 CD in the drive itself.
Then I tried copying the CD contents onto desktop, along with the payloads, extensions... but it still didn't work.

Anyone knows why? Help is very, very, VERY appreciated! Please, thank you in advance!

As an alternative to using the disks, you can download the trial version of the software thru the page linked below and then use your current serial number to activate it.

Be sure to follow the steps outlined in the Note: Very Important Instructions section on the download pages at this site and have cookies enabled in your browser or else the download will not work properly.
