I am trying to update the installfiles for our "win10-x64"-package (from Win 10 1803 to 1909).
After the update, I get this error during Windows 10 installation:
Could not parse or process the unattend answer file [C:\Windows\Panther\unattend.xml] for pass [specialize]. The answer file is invalid.
If I revert the installfiles to "Windows 10 1803" the installation works fine...
I have tried creating a new winpe image from a manually installed Windows 10 1909, but the same error occurs.
Do you have any idea what I am missing?
Alternatively can you upload a unattend.xml-file which you know is working with Windows 10 1909.. Then I can try with that one.
