I am in my 70's and love life, I like to try new things, I sit at my computer several hours every day. I even watch TV on it! I also like to know how things work or in this case not work? MS tells me that the problem is that I purchased the computer in the US but now I am in Europe and bought the win 8 download here in Europe and that is why it will not install, I think this is BS and they do not know what is the real problem. I guess I will try a clean install only I'm afraid of losing win7. It was a Dell free upgrade from win vista.
