DMM incorrect voltage reading

Hi,

I am trying to read voltage with DMM and LabView.

I installed the driver for DMM and If I run one of examples, I get the correct  value ( -0, 000010V)

But If I run another script, the voltage is incorrect, it measures something between -1 and -6 V.

But if I do the same thing with another PC, this script works properly and measures the same value as example vi. So the script should be fine but why it doesn't work on different PC

I don't know if it is driver issue or something else or maybe just settings are wrong

Is there anything that I can try to understand and solve this problem?

Thanks
