Can't use Keysight DAQ Library on my PC

[chaos_]

Hello, I have a very simple code but I see this error every time I try it, also when I tried this code on my friend's computer I did not see any error. It works perfectly if I use VISA for communication but I want to use this library to communicate with my daq.

Also deleted all Keysight apps on my computer and reinstalled them

This library probably needs VISA to work, try installing VISA into your computer and test if it works.

How does this device appear in NI-MAX? Looks like you're using USB connection based on the alias.

You can try following the tutorial here for connecting to a USB instrument:

When an API reports an error but the source string is mostly empty it can be helpful to right click on the error indicator and select explain error. The default error text for 0xBFFA1208 is "IVI: The item does not exist in the collection."

I would check how the device is configured in your friend's computer in NI MAX, especially under the IVI Drivers section.

Yes probably I saw this error for IVI-c driver. When ı try to install this driver I saw this information. But ı couldnt find this driver on my programs and features

If this is an IVI instrument driver then in addition to installing the driver you'll also need to configure the device to use that driver.
