-new_disprd() failed with ‘Instrument Access Failed’

[Manuel27]

Hey there,

so I installed DisplayCal yesterday and it ran very nice the first time around. I then tried to run the calibration again with the Mode set to LCD white instead of generic and since then I always get the error “-new_disprd() failed with ‘Instrument Access Failed'” during the second calibration of the sensor (so the one where you have to put the sensor on the screen). I use Windows 10 Pro 21H2 with a Spyder X.

I already tried uninstalling and reinstalling the Argyll instrument drivers via the Tools submenu. I also tried reinstalling DisplayCal completely (allthough I think that didn’t really work out since all my setting where still there when I reinstalled). Do you have any other things I can try? Thank you!
