U2413, calibration problem, i1Display Studio not found

Hello,

I am trying to calibrate the U2413 monitor on Windows 10 with "i1Display Studio" and the device is not detected? When I run "Dell UltraSharp Color Calibration System" it always appears in demo mode. The laptop correctly detects all devices connected to the display, including the card reader. I have tried several versions of Dell software but it is always the same. I currently have version 1.5.8 from July 2015 installed which I think is the one recommended by Dell on the support page for Windows 10. Calibration device light blinks. What can I do to solve this problem?
