Updateing from widow98

I am using Windows 98 4.10.1998 version. I have windows98 se, but when I try using is to up grade, it tells me tht it cannot perform the udpdate and really failues to explain why. I had A different windows 98 from a different CD, and it allowed meto upgrade with no problems.
What do I do to get this windows above to be able to upgrade, using my Windows 98 se upgrade cd?
Thanks
