officentral Posted August 7, 2006 Share Posted August 7, 2006 I have a Dell Notebook which was reman. and came with XP Media Center. I bought an XP Pro upgrade and when I go to install it it states that the "Product key does not match". I triple checked the characters. I also disable Norton Internet Security & Antivirus. The Upgrade came in a sealed package.I have never had this trouble before with an upgrade to XP Pro. Any ideas? Link to comment Share on other sites More sharing options...
