without going in to gory details.....I have an older laptop with windows vista on it. I need to put windows 98 on it. if I download windows 98 will it override the windows vista? will windows vista, even, allow me to try and do this? I need this done to help my grandson who has an older robotics kit, but in order to make it work, he needs a computer with windows 98 on it. thank you for your time and suggestions. bill new Orleans I am an older guy and not a tech savvy individual...so I would appreciate any advice in simple terms. thank you again.
