That is really not enough information to help you out. Thee should be more of it so that someone can help you. What is the hardware? What is the error? And when do you see the error?
How are you installing it? Cd/dvd or net or something else? Try to give as much information as possible so that members do not have to guess about it and can direct you properly.
Also using a better subject titles help. These titles can have neglective effect.
