I just pikced up a Spyder x and wasn’t completley happy with the calibration it produced. I found display cal was recommended but i’m running into problems trying to get it working.
I got the software installed and got my driver set as an ArgyII device and display cal is detecting it, but I keep getting an error when trying to calibrate the device. It asks me to put the cap on the device to calibrate it and as soon as i hit ok i get an error pop up. “struct.error: unpack requires a string argument of length 12”
looking at the log it seems like it’s finishing calibration but running into an error before it asks me to place the sypder on the screen,
15:18:57,668 Place cap on the instrument, or place on a dark surface,
15:18:57,670 or place on the calibration reference,
15:18:57,670 and then hit any key to continue,
15:18:57,673 DisplayCAL: Waiting for send buffer
15:18:57,673 DisplayCAL: Detected instrument calibration message
15:18:57,674 DisplayCAL: Prompting to calibrate instrument
15:18:59,141 DisplayCAL: About to calibrate instrument
15:18:59,200 DisplayCAL: Sending buffer: ‘ ‘
15:18:59,201 or hit Esc or Q to abort:
15:19:00,457 Calibration complete
15:19:00,457
15:19:00,459 DisplayCAL: Detected instrument calibration complete message
15:19:00,509 Place instrument on test window.

15:19:00,513 └——————————————————————————┘i’ve tried uninstalling and reinstalling both the application and the ArgyII drivers. not sure what else to try.
SpyderX Pro on Amazon

it shows as 45 bytes in size. Should i try deleting that file and reinstalling the ArgyII drivers? I’m assuming that would recreate the file.
