If you accept my advice, use the I1Studio software only for calibrating printers but not for monitors, any monitor. There're free and much better alternatives like DisplayCAL......................
- make a photo of the Colorchecker Classic card
- convert raw to dng with Adobe DNG Converter, make camera profile with Colorchecker software
- import photo in LR using a preset with this profile and lens corrections
- calibrate the monitor with Colormunki and i1Studio software
The i1 software does not see the Munki for registration but it can use the Munki for calibration. One must simply put up with the registration prompt popping up every time the software is started up.
