[OK...The disk I have is from 2001 and it wont do anything its saying the windows on the puter are more updated than the CD.]

mine said the same thing when i did it this summer- but i asked if I wanted to proceed anyway {or something like that} and I clicked yes.

My copy is about that old too.
Yours wouldn't do anything ?or ask if you wanted to do it anyway??
you can always get the all the updates again after the reinstall is done.
it's how I did it.
