The SCXI-1166 is only supported by DAQmx Devices. The PXI-4060 is not a DAQmx device but a traditional DAQ only device.
Table 2 of the NI switches Getting Started Guide clearly state: "The NI 4060 cannot control the SCXI-1130/1166/1167 or SCXI-1193 switch modules."
To recognize the SCXI-1166 you need NI-DAQ 7.0 and create a DAQmx chassis controlled by a DAQmx device like a NI-4021 or NI-4070.
