  • HI reowddy


    you cannot upgrade from 32 bit to 64 bit
    The only upgrade path available currently is from Vista to Win7 - 32 bit to 32 bit   or 64 bit to 64 bit .


    you need to clean install for 64 bit version.

    reowddy, you need to pop the 64-bit install disk in the drive, reboot the machine, and allow the machine to boot from the 64-bit install disk.  (You may need to ensure, in your system BIOS settings, that your machine is configured to boot from CD/DVD-ROM.)


    You are encountering problems becuase the 64-bit install disk has a 64-bit version of the installer on it, which cannot run within 32-bit Windows.  that's why you need to boot from the install disk, to begin the install.


    Cheers

  • Techwrighter , thank you for finally posting a valid response.  I feel like people who know nothing about this subject are randomly responding to questions like these, thus providing the wrong information.  You can absolutely upgrade from 32bit VISTA to 64 bit Windows 7.  If you purchased that $50 upgrade package this past summer then you have received it by now and have noticed that it has a 32bit disk and a 64 bit disk.  As Techwrighter has said you need to boot from the Windows 7 64 bit upgrade disk and then just follow the logical steps from there.  The install disk will then perform a clean install of Windows 7 after reformatting and repartitioning your HDD.    DO NOT WIPE your HDD as other people are suggesting, because then your upgrade disk will not work and you will have to reinstall Vista again.  The upgrade disk will also let you install Windows 7 on a second partition for a dual boot as long as the partition is on the same HDD as your original Vista install.

  • Technically, it is possible to 'Migrate' to any version of Win 7 from Vista. It is not possible to 'Directly Upgrade' 32 bit to 64 bit. (Source - try the 70-620 course!) Note that by http://technet.microsoft.com/en-us/library/dd772579(WS.10).aspx this upgrade path is unsupported. If it goes wrong, Microsoft will not help you. Whether you can legally use the upgrade version in this manner is a matter for the small print on the box and the lawyers.

    Suggest using easytransfer first to save your profile and data to an external hard drive. If possible, do a complete PC backup of your vista PC first. Then boot from the Windows 7 disk and perform the installation. After installation, use easytransfer to get your user account, settings and files back from the external hard drive.

    If the installation goes wrong, you can boot from the Vista Disk and restore your PC from the backup and try again.

    With the exception of the migration from 32-bit to 64-bit (or vice versa) it is "technically" possible also to upgrade install any version over any other version.  All you need do is some rather simple registry editing in the original install, to change the flags which identitfy the installed version to values pertinent to an installation of a 'valid upgrade path' version.  The Windows installer can be 'tricked' into doing something it isn't default-configured to do, in other words.  That isn't necessarily something which it would be 'sensible' to do, but it is something which is 'possible'.


    Point of saying that, however, is simply this:

    I've seen lots and lots of confusion, of late, regarding those publicised "valid upgrade paths".  People see comment from Microsoft regarding 'valid upgrade path' or 'supported upgrade path' and erroneously conclude that the term represents the circumstances in which a 'license upgrade pack' can be purchased used.  That conclusion is most decidedly an incorrect one.  'Valid upgrade path' refers ONLY to the circumstances in which an over-the-top upgrade install can be performed. 

    People frequently assume that an 'Upgrade' pack must be used for an upgrade install.  That's incorrect.  If the 'upgrade path' calls for a clean install, the 'Upgrade pack' has the capacity to perfrom that form of installation too.

    Cheers
