Using the -a flag results in an error. Everything else seem to work
fine. I'm using the win32 executables.

C:\>dispcal -a -r -i94
Offset calibration:
Place instrument on a dark surface.
Hit Esc to skip, any other key to start calibration:
Offset calibration successful
The instrument can be removed from the dark surface.
The instrument can be removed from the screen.
dispcal: Error - dispread failed with 'Instrument Access Failed'

Any ideas?

Yes, it's a known bug, due to weirdness in the USB. I do have a fix, but the workaround is very simple, once you've run with -a, run again without -a (The calibration will be retained by the instrument).
