    Hi all,
    I just installed Beta2 as upgrade of XP.It took a while but worked
    OK. I activated sucessfully and then ran Windows Update. Upon re-boot I
    cannot login to Windows. Get message: "You cannot login because you have not
    activated your copy of windows.Please activate and try again. Error
    Information 0xC004F027 The software licensing service reported that the
    licence is tampered."
    So how do I activate when I can't log in?

    TIA Kent

    Boot to safe mode and uninstall any disk mounting software such as Daemon
    tools, Alcohol 120%, etc....
    This is a known bug and will be corrected in the next build.

    I fixed it! When I upgraded from XP to Vista the install program would not
    let me upgrade until I uninstalled Daemon Tools.I looked for uninstalled
    remains from instructions at Daemon Tools website forums. I could not find
    anything in RUN>REGEDIT >
    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services or
    C:/Windows/System32/Drivers. I see some old left over ATI drivers in the
    Services registry. I recienetly added a nVidia card to use Aero. I deleted
    the ATIxxxxx.xxx entries and files and re-booted. Everthing is working now!

  4. Be sure to report the bug and the workaround to MS. It is a good catch.

    I think it is fixed now. I think the cause was that the XP installation I
    upgraded from had Kaspersky antivirus. It did not seem to be present after
    upgrade but the Windows security advisor thought I had antivirus running. I
    uninstalled Kaspersky and have not had anymore trouble.
