NI RIO is the driver that our RIO devices use. For a PXI 7841R, it uses the NI-R Series Multifunction RIO driver. This can be repaired by going to the Control Panel >> Add/Remove program >> National Instruments and clicking uninstall/change. That brings up a list of NI software on your computer. Select the driver, and click the option to repair it.
