docker toolbox failed to create default vm on win7 due to virtualbox network issue

Docker Quickstart Terminal gives the same error.

$ docker-machine create --driver=virtualbox default

I can see VM default in VirtualBox. I have tried to uncheck the NIC property, but VM default then cannot boot and box gives error:

Failed to open/create the internal network 'HostInterfaceNetworking-VirtualBox Host-Only Ethernet Adapter #5' (VERR_INTNET_FLT_IF_NOT_FOUND).
Failed to attach the network LUN (VERR_INTNET_FLT_IF_NOT_FOUND).

Besides, every time running docker-machine it creats a new NIC, like I cannot use the same #5 (with unchecked property).
