@Amar Abdelli:The machine is not appearing in the default machine pool? If not, make sure the WTT service is started on the client machine. If that appears to work, you may need to open a support case with CSS to investigate why the client and server are not talking.
@Chan lee:There is currently a program requirement in the Windows Hardware Compatibility program that states the pen must have an erase function. The function can be via a button on the barrel, or via a tail end eraser.
@DTTL:It is SKU agnostic since the HLK is not SKU specific. In terms of Hardware Supported Applications (HSA), this is optional. Meaning IF you need to have a Hardware companion app that requires an access to NT service, you can create a HSA to do so in DCH environment.
@bvuong: The HLK controller can only be installed on Windows Server 2012, so that is why you do not see the Controller + Studio install option. You can choose the option to download the entire installation to install on another machine. However, the controller can only be installed on Windows Server 2012.
