Upgrade to Windows 7 fromn Vista Enterprise not possible??


  • I'd tried to upgrade my PC from Windows Vista Enterprise (SP1) to Windows 7 but the installation said, that I've to make a new installation and that an upgrade from enterprise is not possible!

    However, isn't it really not possible to make an upgrade from Vista enterprise with the Windows 7 RC1???

  • In order to upgrade from Windows Vista Enterprise edition to Windows 7, you would need Windows 7 Enterprise edition which will not be available until Windows 7 is RTM (Released to Manufacturing).

  • I saw it on the MS Win 7 TAP site and have downloaded it.  Not sure where else they've made it available.  I plan to upgrade my Vista Enterprise x64.  I'm getting an error during setup, but that's besides the point ... it definitely exists.  Perhaps MS has decided to only make it available to TAP participants.

    What is the "MS Win 7 TAP" and what are "TAP participants"??

    Can you send me a link, so that I can also download the Windows 7 Enterprise-Edition RC1??

    Thank you!

  • TAP is Technical Adoption Program,  it's sort of a formal beta program that MS runs to get feedback from enterprise customers and to help them upgrade to the new technology (  It's by invitation.

  • As I mentioned earlier, the Windows 7 RC will be available in one edition – Windows 7 Ultimate.

  • Just in case you're still looking for the answer, all you have to do is change a registry key in Vista.  Change the EditionID in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion from "Enterprise" to "Ultimate".

  • You might want to include this info on the Windows 7 FAQ page seeing's how the answer over there is very misleading in that it does not mention that you have to have a specific version of Windows 7 in order to upgrade from vista. It also states that you can not do a upgrade from windowsxp to windows 7 instead you have to to a clean install. Why? when so maney people still have XP.

  • Hey, Windows 7 RC is a TEST system that expires some day! Poof, and all your production work is gone!

    I won't upgrade ANY system which I had licensed to that. Use this on test dedicated systems only......
