    The unattend answer file contains an invalid product key


    Hi, I'm using DISM to create a custom image, we use a vlk licence key to install but this isn't being accepted on the answer file. Its definatly a valid key and being entered correctly). I'm just getting the error 'The unattend answer file contains an invalid product key' Is there anything i can do to get around this?

    I have no experience with VLKs or other types of Volume Licensing scenarios. But I get the impression the process has changed for Windows 8. I will give you another link that might help, assuming you have not already seen it.

    But I was wondering, is there a version of Windows that is specific to the use of Volume Licensing? If there was, would it have to be used for the key to work?
