can't communicate to 34405A with Keysight Connection Expert

Hello experts,

I have windows 10 system.  I was able to configure a power supply on a RS232 port and that is functioning.

I'm able to use Keysight Connection Expert to send commands or my applicaiton, no issues.

I have a 34405A DMM plugged in on USB.

Connection expert doesn't see it.  Tried multiple cables and multiple 34405As.   


I do see this, as if I'm missing a driver.   See below.   I installed driver_ivi_matlab_Agilent34405_1_1_1_0_x64 assuming that would help but it didn't.



But pretty surprised, the software has trouble with this DMM.   It was easier to connect to a non-keysight instrument.


Any insight?
