The path name is invalid using IVIDCPwr initialize

Hi, 

I want to control Rigol 832 Power Supply using standards IVI drivers

At first step, I only want to run the example included with LabVIEW "IviDCPwr [MSR] - Output DC Volts.vi"

I have download the instrument IVI driver from Rigol website: https://www.rigolna.com/products/dc-power-supplies/dp800/

I have set up it in the MAX as it is shown at the attached document.

The error appears at the initialitation of the instrument, returning: 

"Error -1074135029 occurred at IviDCPwr Initialize With Options.vi"

Possible reason(s):

Primary Error: (Hex 0xBFFA000B) The path name is invalid.

Complete call chain:
IviDCPwr Initialize With Options.vi
IviDCPwr Initialize.vi
IviDCPwr [MSR] - Output DC Volts.vi

Where is the error?

Thanks!
