I have Windows XP on my computer and want to install SP2. I used the Express install system (since there is only one computer to upgrade). The download went smoothely but during installation it said that SP2 cannot be installed since my OS was not a legal one. Now I know mine's a legal installation but I can't find a way out of it. Is there a way to bypass the checking?
I don't live in any major city so I don't have a Microsoft Customer Support Centre here as well.
PS: Please do not suggest Network Installation. It will take a year on my Dial up.
