Adding a KMS Key for earlier products results in Invalid product key or license mismatch RRS feed

  • Question

  • Hi

    I just installed a Windows 2012 R2 KMS Server using the Volume Activation Feature.

    I was able to successfully add my Windows Server 2012 R2 KMS Key from Microsoft Volume License Website

    I was initially unable to add the Office 2013 KMS key but after installing the Microsoft Office 2013 Volume License Pack (http://www.microsoft.com/en-us/download/details.aspx?id=35584) I was able to add the key.

    Now I am trying to add the other KMS keys from earlier version products such as Windows 7, Windows 8, Office 2010 but eack one results in the same error message:

    "Invalid product key or license mismatch. Please confirm this product key is entered correctly and is valid for this application or Windows edition"

    The update: http://support.microsoft.com/kb/2885698/en-us does not apply to Server 2012 R2.

    Can anyone help?

    Thanks.

    - Andre

  • The 2012 R2 key covers Windows 8.1 and Windows 8

    Although the chart in the link above has not yet been updated to include 2012 R2 the server KMS host key will activate the client OS's as well

    The client KMS host keys would be used in a situation where you only had to activate client pc's and not the server OS.

    There is a activation request count that has to happen for both client OS and Server OS, so many clients had to request activation before they would actually get activated.

    KMS maintains an activation threshold, which requires that the organization activate at least five computers (physical or virtual machines) running a server operating system with Windows Server 2012 or later and at least 25 client computers running Windows 8 or later. The computers running Windows Server 2012 must connect within a 30-day period to active KMS client computers:

  • It should work with just the 2012 key

  • Perhaps I don't understand the use for these KMS keys:

    Don't I use the Windows 7 KMS keys for Windows 7 clients, Windows 8 KMS keys for Windows 8 clients, Office 2010 KMS Keys for Office 2010 clients, etc?

  • No Microsoft assumes that you have a volume license and will activate down level clients that are on KMS.

    The KMS host with have only one key per product family i.e. Windows, Office

  • Okay.

    So I have already entered a key for Windows Server and Office.

    I now have to enter a key for Windows Clients, right?

    So why doesn't the Windows 8 key work for clients...or is it that I need to apply the Windows 8.1 KMS key?
