> "Then, the recommended solution, for users of Colormunki, Is to drowngrade only the CM driver to 1.4 version (if it is possible) or to downgrade the driver and the whole application to the 1.4 version?" I’ve perform today some tests. It seems that source of the problem is chartread.exe not driver.After checking all possible combinations I finally finish with driver from v.1.6.0 and chartread.exe from 1.4.0 – this tandem works for me.
