    From a technical point of view This would not prevent you for doing what you want to do - and as long as you have a qualifying licence for the upgrade hanging around, should not have a licencing implication, (XP is ideal as this requires a fresh install)

    If you have the 64Bit install disk from the 3 pack it would probably be best to install from that (fresh install no need to actually upgrade).

    Of course the easiest way from a licence point of view would be to retain the Acer windows and run the Linux in a Virtual machine, but I'm sure you have good reasons for doing things the way you intend.

    Here another version:
    • Save this script to a text file.
    • Change the extension of the file to *.vbs
    • Run it.

    Code:
    Set WshShell = CreateObject("WScript.Shell")
    MsgBox ConvertToKey(WshShell.RegRead("HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\DigitalProductId"))
     
    Function ConvertToKey(Key)
        Const KeyOffset = 52
        i = 28
        Chars = "BCDFGHJKMPQRTVWXY2346789"
        Do
            Cur = 0
            x = 14
            Do
                Cur = Cur * 256
                Cur = Key(x + KeyOffset) + Cur
                Key(x + KeyOffset) = (Cur \ 24) And 255
                Cur = Cur Mod 24
                x = x -1
            Loop While x >= 0
            i = i -1
            KeyOutput = Mid(Chars, Cur + 1, 1) & KeyOutput
            If (((29 - i) Mod 6) = 0) And (i <> -1) Then
                i = i -1
                KeyOutput = "-" & KeyOutput
            End If
        Loop While i >= 0
        ConvertToKey = KeyOutput
    End Function
    There you can see that the encrypted key is stored in registry key:
    HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\DigitalProductId
    at Offset = 52

    And that the key only includes this letters and numbers
    BCDFGHJKMPQRTVWXY2346789
    And no "AEILNOSUZ015 allowed.

    Do you still have it installed on the desktop? Unless otherwise stated in the EULA, a license key may only be used to activate an installation on a single machine. You state that you have already installed it on a desktop, which would explain why you weren't able to on your laptop.

    you can't have the key activated on two machines or more at the same time or else everyone in the world use the same key and not buy windows keys at all. I suggest get a different key or install something else that you have like xp or w/e that has a key and if you have no keys you can have something like ubuntu ftm till you can get another windows key

    Hello Matt, and welcome to Seven Forums.

    Unfortunately, the programs will not be able to show you your product key number if you have not already entered and activated it in your Windows 7.

    You'll need to contact the MSDNAA from where you got it to see if you may be able to get another one sent to you.

    Hope this helps,
    Shawn

    Sorry I haven't been enough clear ;]

    My windows is activated and it works, however I am planning to reinstall it and I need my key to do it, which I have lost!

    Do you know what could be the reason why all the programs dont work?

    Thanks.
