Please insert cs3 master collection disc 1 into drive

i'm unable to install cs3 master collections on my win xp.
i keep getting "Please insert cs3 master collection disc 1 into drive E\ to continue installation".

i downloaded this straight from adobes website.
the adobe cs3 folder resides on my desktop.

my current config:

win xp
2 gigs
intel core 2 duo
win service pack 2

i searched extensively on both google and the adobe forums and didn't come up with anything solid to resolve this issue.

any help will greatly be appreciated.

thank you
