Updating Vista Home Premium to Ultimate doesn't work

    Hello guys

    I have a laptop with Vista Home Premium installed and bought
    Vista Ultimate directly from Microsoft in Dublin - no update but the full
    boxed version. How can I update my existing version to Ultimate without
    losing any data? My Ultimate DVD complains that a later version of Windows is
    already installed and it abort the installation process. I wonder what
    happens if I simply boot from the DVD and start the installation using the
    existing partition etc. Will I lose my settings or will only different files
    be updated? Exchanging the serial number did not work.

    Just for clarification: I did not buy the AnyTime Upgrade which I heard
    would come with an update tool. I might need that particular tool as well but
    can't find it and wouldn't want to try it and lose all my data.

    I hope that my situation isn't too unique and someone has experience with.

    Thanks a million for any help!
