You need to check that the Argyll driver is running. In Device Manager it should list "Argyll LibUSB-1.0A devices" and under that "Colormunki (Argyll)". See <http://www.argyllcms.com/doc/Installing_MSWindows.html? and the "Adding Argyll drivers to existing drivers:" section on how to switch to the Argyll drivers. Graeme Gill.
