@ Reinhard Ostermeier - If so, I can think of two ways.
You could create your own installer using the Wix toolset and difxapp with our driver files.
The second, and probably easier way, is to use DPInst (http://msdn.microsoft.com/en-us/library/windows/hardware/ff544842(v=vs.85).aspx). You can find DPInst in the Windows driver development kit. Once you install that, you can find dpinst.exe in a path similar to C:\WinDDK\7600.16385.1\redist\DIFx\dpinst\EngMui\amd64. Just take dpinst.exe only and place it in a separate folder with our four driver files that you can find by installing our SDK once. Run dpinst.exe and it will install any drivers found in the same folder as it. You could possibly automate that with a batch file and distribute the exe and our drivers to your machines. Once you install the drivers that way, you will see two new entries in the Programs and Features part of the control panel and the drivers should work as normal.
The second method appears to register the drivers properly, but we cannot test or support either method in any way nor can we say how it will interact with a future install of our SDK or if it will work with FEZ Config.
