Query: I wasted my money on this scanner

I bought this scanner from Amazon, and while the price was great, the money that I spent on it was completely wasted, since this scanner is not compatible with my computer! I have a COMPAQ PRESARIO 7360, which does not use a Pentium chip, and so my computer does not recognize this scanner. So beware - this scanner is not compatible with all computer, something that Microtek does NOT make the buyer aware of!
