Chaps and chapesses, please forgive the bone question but I'm stuck. I've used search and Google but I can't spot the anwer; but I may just be too thick. A dear friend is trying to reinstall Windows XP on her computer. She puts in the correct product code, as per the sticky label on the computer, but it won't produce an activation code; just a line of dots. So it accepts the product code but won't show the activation code that the Microsoft site want to provide the activation key. Help! please.
