Windows – How to upgrade from windows vista 64-bit to windows 7 64-bit using MSDN DVD

windows 7windows-vista

Every time i run windows 7 set up i get the following compatibility report:

The following issues are preventing Windows from upgrading. Cancel the upgrade, complete each task, and then restart the upgrade to continue.

  • You can’t upgrade 64-bit Windows to a
    32-bit version of Windows. To
    upgrade, obtain a 64-bit version of
    the installation disc, or go online
    to see how to install Windows 7 and
    keep your files and settings.
  • 32-bit Windows cannot be upgraded to
    a 64-bit version of Windows. To
    upgrade, obtain a 32-bit version of
    the Windows installation disc.

This message doesn't make any sense. What to do?

UPDATE: It seems that MSDN Disk is somehow defective or cannot be used for updates. According to social.technet.microsoft.com nobody was able to use it for update.

No - You have a MSDN subscription which gives you access to both disks, but you must of downloaded the incorrect one. For example, for ultimate, the x64/64-bit is called - en_windows_7_ultimate_x64_dvd_x15-65922.iso and the x86/32-bit is called en_windows_7_ultimate_x86_dvd_x15-65921.iso Also, there is a 700Meg difference in size, 64-bit is 3,075.30MB where as 32-bit is 2,385.99 MB – Wil Oct 28 at 21:22

I'm not sure why you are telling him what he has, how would you know better than him where he got it from?

I have received it in mail. Disk 4618 November 2009 - Windows 7 Ultimate (x64 and x86). And setup indeed asks me to select version. – alex Oct 28 at 21:25

I have a MSDN and Technet Subscription - I have never seen a dual disk - nor can I think off the top of my head of any Microsoft software that has been released as x86 and x64 on the same disk. The closest I have seen is a licence key on the back of a Ultimate DVD I got from an event that states "licence key for 32 and 64 bit" (or x86 and x64 - I forget!). I would double check your disks, or if possible, can you take a picture and block out serial key/personal stuff, and I will try to help you further. – Wil Oct 28 at 21:50

Wil, the MSDN disc for Windows 7 has BOTH 32 bit and 64 bit versions on it, I'm looking at it right now! It won't work for an upgrade from Vista 64 to Windows 7 64 bit for various reasons, see this link for more info -> Technet Forums

I'm thinking if the people at MSDN were thinking clearly they should have sent it on seperate discs. You can download the ISO and it will work just fine but, thats a BIG file to download.
