Can I upgrade Windows 7 32-bit to Windows 8 64-bit?

Dhaval Kaneriya December 16, 2012

I’m planning to buy Windows 8 upgrade version. I’m currently running Windows 7 32-bit, but I want to install Windows 8 64-bit. Will the product key work for clean installation because there are cases in which product key didn’t work for clean installation.

So what should I do? I already have my backup and I also have 4 GB DDR2 RAM installed.

    No u cant run the setup in windows if it is 32bit

    If ur processor supports 64bit u can do it by formatting n doing a clean install

    The product key will work on both 32-bit and 64-bit, the bigger issue is how are you going to get a 64-bit copy of windows 8.The file it gives you when you download Windows 8 is 32-Bit because your current install is already 32-Bit. You could download the install file on a 64-Bit windows machine (the link for downloading is in the receipt you got in the email after purchase) and burn the iso file and then install off there on your machine.

    If this is a big pain, sticking on 32-Bit won't hurt unless you are needing more than 4GB of RAM :) .....

    (Also, you need a processor and motherboard that supports 64-Bit)

    No upgrade key doesnt work for clean install and you have to do clean install if you want to go to 64 bit

    If your processor supports 64 bit OS, yes you can upgrade

    It depends upon your hardware. If your pc is a 64-bit pc then you can install the windows 8 64-bit but if you have a 32-bit pc then you will have to install a 32-bit windows 8.

    First run the Windows 8 Upgrade Adviser to see if your computer is compatible. If your computer uses DDR2 it may be to old to run 64 bit Win 8.

    You can't upgrade from 32bit to 64bit and Upgrade Advisor would only upgrade you to 32bit if you have 32bit installed. You should get Windows 8 Pro Upgrade Media which comes with a selection of the "bit" version and the appropriate key.

    It's possible. You just need to make sure you actually have a 64-bit system, then you'll need to buy the retail Windows 8 64-bit version and not an upgrade.

    Also, you need to have a 64-bit CPU, which I assume you do if your computer is even semi modern.

    Upgrade Advisor will only provide you with the same platform type (32-bit/x86 or 64-bit/x64) as the system you’re currently using. If you start with 32-bit, you get 32-bit.

    you will need to purchase the retail Windows 8 Pro Upgrade media. This package provides both 32-bit and 64-bit media, so you can choose which to use. In case this isn’t obvious, you can’t actually do an in-place upgrade from a 32-bit version of Windows to a 64-bit version fo Windows 8. Only clean installs (“Custom” install type) are supported.
