    I downloaded and activated Win 7 Ultimate (thank to all of you).

    Now I would like to know if it is possible (or necessaery) to add the x64 bit part of Win 7 Ultimate to the present installation

    Thx in advance...

    You can't "add" 64 bit architecture to a 32bit installation of windows.

    You can on the other hand create a dualboot between win7 x86 and win7 x64.

    Just start the installation of win7 x64, and when asked on which partition you want it, make sure you install on a different partition.
    The entry for win7 x64 will get added to the bootloader automatically.

    After installation is done, you will have the ability to choose the os you want to load when booting up.

    Thx for quick response...

    Now I currently have a dual boot with XP Pro and Win7 Ultimate with an empty partition of 12 gig.

    Will this set up work for what you suggested.

    If so, where do I download the installation for x64.

    I have already downloaded the 2.34 gig listed earlier in a thread this the download that I need?

    I recall no option to select either x86 or x64 on the first (x86) install ... it was the default.

    maybe, you just downloaded an x86 image file only(does not have x64) and not an AIO (All In One) image file.

    also, does your hardware (CPU & motherboard) support x64?
