VEE not recognising instruments

I have a GPIB/Ethernet gateway which is connected to a E3643A power supply.

Using the Agilent Connection Expert I can find the instrument and use Interactive IO to send and read simple commands (*IDN?, etc.).  Using the IO Monitor I can clearly see that the instrument is being connected to via VISA and the commands are being sent, responses read.  That's all great.

However, when I try to use the same instrument, on the same PC, via VEE (Pro 9), I get a simple error message:
No such instrument or incorrect address for device 'PSU'.
Error number: 800
VISA viOpen failed

In the IO Monitor, nothing appears, not a viOpenDefaultRM, viOpen, nothing.

Has anyone any ideas on where I need to look to solve this issue?
