I use for a long time DispcalGUI with Windows 7, 32 bits but now I have installed Window 7, 64 bits on the same computer. I have installed ArgyllCMS et DispcalGUI but it fails to see my two displays as well as the Colormunki colorimeter. I have no idea because I think that all the settings are the same as were used with Windows 7, 32 bits. Is there a problem with W 7, 64 bits ?
Thank you for your help, and sorry if my English is not very good.
