I get the same message error as you, with my Windows 2012 server based on 64-bit architecture.
I checked the code, the error value is returned from the windows function GetLastError :
2 (0x2) : ERROR_FILE_NOT_FOUND
This error occurs when the windows CreateFile function is called on the Ipfw I / O device.
If the specified file or device does not exist, the function fails and the last-error code is set to ERROR_FILE_NOT_FOUND (2).
To do this quickly, I think that the “Ipfw” service is missing, it displays as correctly installed, but it is not.
