I got the old computer from a friend with entire system down, so I try to reinstall Windows XP home edition. On the end I was asked to put in the product key,I have input the key that is on the sticker attached to the system and I am told that it is incorrect. I didnt see the option to do a keyless installation. What should I do now ? the installation CD may be older than this computer, Is this a problem? HELP!
