All the necessary drivers and utilities for USRP SDR are included in the GP-Simulator package. But if during the installation you forgot to turn off the antivirus, some of the components may not be installed.
If your connected USRP is not listed in the "NI-USRP Configuration Utility" or you can not find the utility itself, try to reinstall this toolkit from National Instruments: https://www.ni.com/en-gb/support/downloads/drivers/download.ni-usrp.html#467627
