Hi,
Have you installed the DAQ driver. If not, then you can find it for your particular device at this
site. If you have installed DAQ, make sure it is the most up to date driver. This broker file is a part of the driver install, and it should be in this directory:
C:\Program Files\National Instruments\Shared\LabVIEW Broker
I hope this helps. Have a Great Day!
George
