contribute CS3 won't load

[pattsie]

I have a Dell Inspiron 1720 with 2048MB memory and I'm trying to load
Contribute CS3.
The version I have is for Intelcentrino(which I have),Windows Vista (which I
have).
I've tried stopping the firewall with no luck.
It seems to be crashing every time.
When I click on 'Set Up' the Adobe 'Set Up' box appears for a couple of
seconds then it disappears.

What am I doing wrong!!!
Help I'm going MAD.:mad;
