Starting created service using sc.exe throws error: “[SC] StartService FAILED with error 129.”

Question

I create the service using following commands: sc create MyService binpath= "C:\\Path\\MyDriver.sys" and the returned message is: [SC] CreateService SUCCESS , but once I want to start this service using: sc start MyService I get the error: [SC] StartService FAILED with error 129. . Have you any idea how to fix this error and start service properly? I've seen this , but there's no proper answer. Thanks in advance.

Error code 129 is ERROR_CHILD_NOT_COMPLETE (ie the application cannot be run in Win32 mode). You created a user-mode service since the default is type= own (ie SERVICE_WIN32_OWN_PROCESS when calling WinAPI CreateService ). However, you're trying to run a kernel-mode driver, which should be type= kernel (ie SERVICE_KERNEL_DRIVER ).
