I would normally suggest uninstall and reinstall but you have a problem without the original disc. As luck has it I have 2 copies of Quicken 2004. I had Quicken XG and when Intuit stopped support they sent me 2 free copies of Quicken 2004. I recently installed Quicken on a new computer without any registration problems. It activated automatically. If you want a copy let me know and we'll try to work out a way of getting one to you.
