I would have thought that inserting the System Recovery CD from your old setup may start the system recovery process - therefore reverting your system back to the way it originally was. I'm not sure if you could gain access to the Works folder on the CD without running the system recovery process.
You may be able to cancel the recovery process after inserting the CD when you are logged on (NOT before the OS has booted up). You may then be able to browse the CD's contents in Windows Explorer to find the Works setup folder you need.
You could try this, although there are no guarantees that it will work!
