    Upgrade Win7 32Bit to Win8 64bit


    I have windows 7 32 bit installed on 2 separate drives (dual boot).
    On one of the drives I want to install Windows 8, but want to use the 64 bit version to see if it runs a particular programme better taking advantage of more memory.

    According to MS upgrading using the Install Assistant or Advisor will not upgrade 32bit to 64bit so I cannot upgrade at the lower price and have to buy the full install cd.

    Is this actually the case, or is there any work around that will allow me to download and install the Win8 64bit upgrade at the lower price

    When downloading the upgrade you need to

    information   Information

    If you need to download 32bit Windows 8, download from a 32bit PC.
    If you need to download 64bit Windows 8, download from a 64bit PC.


    Clean Install with Windows 8 Upgrade

    You will need to wipe the partition first to upgrade from x32 to x64.

    You can do a clean install with the upgrade, just not an "in place" upgrade of 32 to 64. I've done it several times.

    Thanks Guys.

    This raises 2 other questions if I may.

    - Does anyone know if the same product key works with both the 32 bit and 64 bit versions.
    - The only 64 bit PC I have access to is a friend who is now running Windows Enterprise 8. Would I be able to download the upgrade for 8 Pro in his PC?? If not, I guess there is no where else to get hold of the upgrade installer other than download from MS?

    Thanks, so if I can't download on my friends Win8 pc, I could purchase the upgrade on my 32bit PC to get the legit key, now I just have to find a way of downloading the 64 bit installer.
    If anyone has any suggestions I'd appreciate hearing.

    Thanks.

    I just ran the Upgrade assistant and after checking the hardware/apps it went online to 'prepare a few things' then came back with a message saying that the download upgrade was not available in my country/region - was connected to the GB MS site at the time.

    Is this usual??
