Server 2008R2 product key in autounattend.xml

Hi All

I've been working on an unattended 2008 server build for my company and have the non R2 versions working perfectly. The problem I have is around putting our product key (MAK) in the unattended file with 2008R2.

If I include the key then I get a message saying 'The unattended answer file contains an invalid product key. Either remove the invalid key or provide a valid product key in the unattend answer file to proceeed with the Windows installation.' All the other setting from the autounattend.xml are applied correctly.

If I leave the key out of the answer file and let the server build complete without it and then 'Activate Windows' and use the same key it activates fine??????

Has anyone successfully intergrated thier MAK key in an unattended file being used with Server2008R2? do you put it in the same section as the non R2 versions?

Any help greatly appreciated

For info here is my autounattend.xml
