    upgrade from vista 32 bit to eight 64 bit


    Hi, I had until today a windows 7 x64 but it was not genuine. Now I want a genuine copy of windows eight, so I restored my pc to the oem windows vista home premium 32 bit that came when I bought it.

    I bought the upgrade for 29.99+15 for the dvd, and now it is downloading.

    but now I wonder, will it install a 32 bit version of Eight? I have 4gb ram so I need the 64 bit version... but it didn't ask me to choose which version I want, neither in the site says anything about the x86 and x64 versions...

    Hi I'm wondering a similar thing i.e. trying to find the best way to upgrade from vista 32 bit to win 8 64 bit. You say you bought the dvd but then mention that its "downloading". I thought the dvd would be sent by snail mail, do you have any updates on the process?

    If you need 64-bit, I got Win8 Pro 64-bit by installing Windows 7 64-bit (didn't enter a product key, just left it in 30-day trial mode) and running the Upgrade Assistant. It seems like Microsoft isn't checking product keys for your existing software at the moment.

    The upgrade assistant gave me an option to ship me the backup dvd for 14.99 more (so I spent 45 instead of 30)... maybe this is only in europe

    From what I understood, the dvd contains both the 64 and 32 bit versions, and the licence is valid for both the architectures...

    now I am stuck with this 32 bit version and there is no way to get the 64... I'll have to wait for the dvd to be shipped, or download it from unofficial sources...

    Windows7, 8 pretty soon


    I have this confusion too...i'm on windows 7 32 bit home basic and i want the 64 bit win8 pro.
    If i use the upgrade assistant i'm not sure if it'll download the 32 or 64 bit version. My processor supports 64 bit architecture as i'm using 64 bit ubuntu on a vm.
    But if the assistant downloads the 32 bit version i'll be really really pissed.
    I know the assistant does not allow cross architecture upgrades so i'm led to believe it'll download the x86 even though my system supports x64.
    So my options now? Confused.
    If it downloaded the x64 win8 pro then i'll happily burn the iso to a dvd and do a clean install. If not..i'll have to by the dvd for a higher price.
    I'll be glad if someone can verify whatever i just said.

    I can confirm it will download the 32 bit, done the same with vista.

    they say you should first install win7 64 bit (even in trial) and then run the upgrade from that.

    The ISO should say, x86 or x64

    Click image for larger version

    x86=32bit x64=64bit

    maybe I found a way to download it. In the invoice email there is a link to download win 8. maybe if I run that file (windows8_setup.exe) from a 64 bit environment, it will download the 64bit version!

    That is a .exe huh! Not sure how it works.
    Wish they gave an option to choose the .iso and download it directly.
    Check what that .exe does n let us know if possible, might be the same as upgrade assistant.
