I've been tearing my hair out all day! I have an older 34401A (firmware rev 3-1-1), and have connected it to my windows 7 x64 machine via a USB-RS232 converter (a Tripp-Lite Keyspand USA-49WG). I have installed the latest IO libraries and BenchVue software, and the latest drivers for the 34401A. I am able to successfully install and communicate with the 34401A through the Keysight Connection Expert, but I have had little luck within the BenchVue software.
At one stage I did reinstall the BenchVue software, and after a PC reboot, I was able to communicate with my 34401A and perform some measurements. Halfway through the measurements, my PC reset unexpectedly, and when it rebooted, I could no longer connect through the BenchVue software.
In the Keysight Connection Expert, I can 'Send Commands to this Instrument' and everything seems to be working fine. In the BenchVue software the 34401A comes up under the hidden or unsupported instruments with the green tick (I guess indicating that it is hidden, but supported). The 'show' button is grayed out, and try as I may, I cannot get the 34401A to show up!
I have attached a couple of screenshots to help explain what I am seeing.
Thanks in advance for any help you can offer!

Agilent 34401a Driver
Agilent 34401a Accuracy
The 34410A and 34411A are backward compatible with the Agilent 34401A multimeter and support a 34401A emulation mode. You will find a detailed comparison of the 34401A. I mentioned my search through ToolGuyd’s Twitter page, and an Agilent social media rep sent me a link to Agilent’s general YouTube page. One of their recent promotional videos featured their E3631A power supply and made mention of Agilent’s free BenchVue software. 34401A, 34405A, 34410A, 34411A, 34450A, 34460A. I am a Mac user.
