installing adobe cs3 designer edition Options

[Melissa]

So my friend gave me a burnt cd of the Adobe cs3 suite that her friend had given her. She told me that it installed fine on her computer - I THINK it's an XP, but I'm not sure - but when I try to install it, it goes through the process, then right before it's about to install, it tells me to insert the cd, but ... the cd's already inserted. I'm not sure what the deal is. I'm on a Window's Vista if that makes any difference at all.

I'd ask her if there's another cd or something, but it's 1:30am and I doubt she's around.
