setup box.....? okay so i have a MAC.
i downloaded the trial version of adobe photoshop cs3.
theres this little thing on my desktop, it says Ps and theres a cd on it.
i open that up and i see two things-
a box thats blue and closed that says Adobe Photoshop Cs3
and the other says Read Me

i open the CS3 one
then i see in the box thing:
bootstrapper.dmg
resources(folder)
deployment.xml
payloads(folder)
and setup(which is another blue box)

i cannot open setup, when i click it, i see it in the bar at the bottom of the screen and it looks like its about to start bouncing and work. but then it doesnt and it goes away....
HELP?
im bad with macs so try to make this easy :/
