I've been trying to run the calibration application (version 2.2.0 on a 64 bit Windows 7 machine but have been receiving the same error message "Failed to read the prescriptions" each time the application launches.
When I click "Ok" to clear the error message, the "Calibrate Display" window appears but the pull-down menu for the "Choose the Display Preset" list is completely empty.
The LP2480zx's USB cable is properly connected and the monitor is connected to the computer via DVI.
Has anyone experienced this or know the way around this issue? I wrote to x-rite, the makers of the Colorimeter but they replied that this was a software issue that had to be taken up with HP.
Would appreciate any advice on this.
