i1Display Studio “Instrument Access Failed” error

[KLAIM]

Hi,

I bought a set of i1Display Studio last week and have tried to calibrate my laptop with displayCAL.

It doesn’t work at all. X-RITE software, i1 Stduio, can calibrate but displayCAL doesn’t;

it shows error message – Error – new_disprd failed with “Instrument Access Failed”

I did google and searched here but I couldn’t get right solution.

My system

OS: Windows 10 (64bit) version 2004

Graphics card: RTX 2080 Super Max-Q

Calibrator: i1Display Studio

Display: 15.6″ OLED 4K (Laptop)

I really want to calibrate it.

Many thanks in advance.
