Finding it hard to download the Genuine Vista starter

I have here with me a genuine Windows Vista starter and I am trying to run the set up of this thing but I find it so difficult in doing so. As I tried to run the set up, a message will show asking for the key numbers that is said to be found inside the box but I dint found anything that looks like whats been shown. I am planning to go to the store tomorrow where I bought my Acer Aspire laptop and ask for help. I am sure that they can advice me what to do to download my Genuine vista starter.
