NI 4431 - Found by DAQMX, but NOT found by Labview instrument driver

Hi

I have a NI 4431 which has been working well.  It is recognized by MAX 19.5 and I am able to create tasks for it to make measurements, etc. 

However, I am unable to use it within LabVIEW as the instrument driver finder cannot find it.  I am able to find other instrument drivers such as my Agilent oscilloscope without issues. 

Can you tell me what am I missing?

Thanks!
