Go from 32 bit to 64 bit

I want to upgrade to 64-bit windows vista from my 32-bit system. can I use the same product key, which I had previously used for 32-bit or I need a new.

thnx

Each product requires a separate product key.  One 32-bit will NOT work with a 64 bit system.  And you can use any one product key on one computer at the same time.  Make sure that your system can be upgraded to 64-bit (and that you have access to all the device drivers you need and no incompatible software installed) before even attempting this upgrade - I suggest you to check with the manufacturer.

Here is an article on the choices and options when you perform this type of update: http://support.microsoft.com/kb/932795.

I hope this helps.

Good luck!

    I just bought a Toshiba L750. After learning of the default Windows 7 installed is Windows 32 bit, I decided to go Recovery Wizard from Toshiba upgrade to 64 - bit. However, the process is stuck to the system performance of note, that repeated several times for 2 hours.

    Given that I guessed that screen performance of system just note one full screen of a normal process of Windows, so I pressed the button Windows start to display the taskbar which showed a component of Adobe installation process has failed. In any case, I clicked on the install Adobe on the taskbar button and close the window.

    The note system performance then continued with about 10 steps ahead after 15 minutes. All well done.

    So the trick is to close a window of the installation components that get stuck. Hope this helps some Toshiba laptop users out so hard.

    A suggestion from bits to the team of Toshiba laptop:
    The full screen of the Recovery Wizard is good to hide technical details from users. However, if hang in some components, like the Adobe component I've seen, this will be confusing and advises current defects if the end-user following some in the thread above, legacy because of some missing components and the wrong configuration. It is preferable that the wizard of recovery to exit full screen at a given time, or the wizard handles error scenarios better.

    I don't know what you mean by "xp p2. Do you mean that you have Windows XP Service Pack 2 installed?  If you want to run a 64-bit operating system, you must ensure that you have a processor 64-bit capable. You'll also need 64-bit drivers for all your hardware for any 64-bit operating system you want to install.

    Is this an older machine? Is there a reason you want to move to a 64-bit operating system? You should also be aware that you cannot move to a 64-bit to a 32 bit OS OS; You must do a clean install. MS - MVP - Elephant Boy computers - don't panic!

    Can I move from a 32-bit version of Windows to a 64-bit version of Windows...

    Lol if you are currently running a 32-bit version of Windows, you can only perform an upgrade to another 32 - bit windows version. Similarly, if you run a 64 - bit windows version, you can perform an upgrade to another 64 - bit windows version.

    If you want to upgrade from a 32-bit version of Windows to a version 64-bit Windows Vista or vice versa, you will need to back up your files, and then choose the Custom option duringWindows Vista installation. Then, you will need to restore your files and reinstall your programs. For more information, seeinstallation and reinstallingWindows Vista.

    Another extract of choice of Installation for Windows Vista (64-bit):

    Upgrade of an operating system from 32-bit to a 64-bit operating system If you buy a updated version 64-bit of Windows Vista with the intention of installing on a computer that is running a 32-bit operating system, you must install Windows Vista by starting the computer from the 64-bit Vista installation DVD.

    Important Do not remove the previous operating system before you start the Windows Vista installation. This is because the Windows Vista Setup program verify that your current operating system license supports the installation of a 64-bit upgrade version.

    When you have 32/64-bit, you must choose 32-bit or 64-bit, not use both.

  • Switching from 32-bit to 64-bit os.

    My operating system is Windows 7, 64-bit home edition.  For some reason any property that it runs on a 32 bit os.  Why is this and how do I solve this problem?

    Are you sure that you are really under 64-bit Windows? 64-bit systems can run 32-bit versions of Windows too.

    Click Start, right click on computer

    Click on properties

    Go to the System section > system type:

    There it will list whether the processor is x 64 based processor . In my case, I have processor 64-bit capable.

    For users of Windows XP, Vista or Windows 7

    You can determine if your processor is 64-bit capable in using an free tool called CPU-Z. You can download it here. Once you have installed, double click on it and it will scan your system. Click the CPU tab and look in the Instructions field, want called AMD64 or EM64Tinstruction set. If you see them, your processor is 64-bit capable.

    When the 64-bit processors have been introduced more than 10 years ago, one of the advantages of x 86 - x 64 has been the ability to still run 32 bit OS on 64 bit unmodified processors and harness advantages such as compatibility and real help from 9% in performance running 32-bit code and apps on such an architecture of processor.

    There is more to running a 64-bit on 64-bit operating system, other factors determine if it is worthwhile.

    Windows 7 64 bit comes in handy when you need to deal with at least 4 GB of RAM or more. Windows 7 32 bit can use up to 3.2 GB of RAM. Because the address space of memory is much larger for 64-bit Windows, this means that you need two times more memory than the 32-bit Windows to accomplish some of the same task, but you are able to do much more, you can have more apps open, do things like run a virus scan in the background it will affect the performance of your system. 64-bit Windows 7 is safer too, malicious code cannot easily infiltrate it, drivers are more reliable because they must be signed before it can work with 64 bit Windows 7.

    Regarding compatibility, you need device drivers 64-bit hardware devices, you may have. In addition, there is no 16-bit subsystem in Windows 7 64-bit, which means, your applications must be 32-bit only, not 16-bit Installer or programs uninstaller.

  • How to migrate my upgrade from 32-bit to 64-bit Windows 8

    Hello to everyone

    I bought the Windows 8 upgrade online to update my Windows XP installation to 8.

    However, I only had the 32-bit version, which I didn't discover until Windows 8 32-bit was already installed. It's a disappointment because my support 64-bit Windows 8 and for this reason it is accurate that I wanted to move to Windows 8.

    I followed the instructions on the Microsoft support site now who tell me to buy separate installation media. It means that I have an official DVD with Windows 8 upgrade to 64 - bit.

    My question is how should I proceed from here? Can I just install Windows 8 64-bit directly above the windows 8 32 bits already installed on my hard drive and do this by booting from the DVD?

    I tried to do last night, but the only result was that Windows 8 32-bit re-installed itself hard disk and deleted applications and data on the hard drive.

    The only solution I see would be to have to re-install my old Windows XP and start the 64-bit DVD to install it directly on the. And frankly, this seems like an unnecessary pain.

    Any help with going from 32-bit to 64-bit Windows 8 using my version of upgrade would be greatly appreciated. Honestly, I do not understand why Microsoft has made this process so difficult.

    Cheers, BillyBob

    Hello Andrew

    Thank you for your quick and comprehensive response. I see from your answer that it is possible to 'upgrade' to Windows 8 64 bits from an installed version of 32-bit simply start from the 64-bit DVD and by taking the necessary precautions to copy data and files in advance.

    Thanks especially for the guide step by step designed to make a "custom installation". It is the exact procedure, I was looking to have confirmed. I couldn't do this job yesterday, but it may have been because, inadvertently, I activated the "system reset" function of the 32-bit Windows 8 on the hard disk when you are looking for the option to open a "custom installation".

    I will try that tonight and get back to you (and any other Googling their way here) a confirmation if it works or not as I found it difficult to find detailed information on this procedure elsewhere.

    Just to be clear 100%: it is possible to use the DVD from an upgrade VUP to do a clean install 64-bit on a 32-bit Windows 8 installed version, right?

    Best regards, BillyBob

    Please note, an upgrade is not possible by either from installing from a Windows version, or by booting from the disc for 32 to 64-bit scenarios.

    Yes, you can use the disk to upgrade to migrate from 32 to 64-bit.
