Bob,
You need to install the Agilent VXIplug&play driver first. On the LabVIEW driver download page, there is a link to the Agilent's VXIplug&play driver but it is currently broken and we are in the progress of fixing it. Here is the correct link to all Agilent's VXIplug&play drivers:

The VXIplug&play driver for your model can be found here:

I hope this helps.
