Device Manager won't recognize driver for Agilent 34401a

Hi

And what does MAX tell you about interfaces and software?

And the interface you have , what are the lamp colors?

Yellow or green when plugged in and connected to the agilent device?

And the agilent device is set to gpib?

It seems that you installed everything you need but something is wrong.

Your device (the agilent one) does not have to show up in windows devices because it is connected via USB to GPIB but it should show up in MAX when searching for devices.

According to Max, the device is there but Windows doesn't have any drivers associated with it. The Multimeter is USB\VID_3923&PID_702B\5&18054507&0&1.  It has LabVIEW 2020 f1 (64 bit), NI-488.2 2020, NI-488.2 Runtime 2020, NI-VISA 20.0, and NI-VISE Runtime 20.0 listed under the software. 

I don't know what you mean by lamp colors - the lights on the GPIB-USB plug don't light up when they are plugged into my computer (but do when plugged into the laptop where the system is working). The agilent device reads out a GPIB address when it is powered off and on again, so it is set to GPIB.

So it boils down to your device not being recognized by the machine.

Maybe a real NI guy can help you. Sure it is something that is installed in 32 bit and not 64 bit but I never used to the 64 bit version, maybe next year when I maybe need more memory for my program.
