Display Driver Sample gives error code 31 RRS feed

  • Question

  • I compiled and installed the Kernel mode display-only miniport driver (KMDOD) sample on a Windows 8 x64 machine.  It says it installs correctly, but then says "This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)."

    I'm following the manual install instructions given on the sample page (i.e. installing the certificate, turning on dev mode, etc.)

    Does anyone know why this happens?
