Hi zoyd,
I just deleted all relevant ordners
use`d your link to reinstall
I did and started HCFR out of Win7, ALL programms, HCFR
- attached you will see the marked buttons, on those I only get a black window and none working pictures.

opend a new session
- found my C6 as: Xrite i1 DisplayPro, ColorMunki Display (I do not use the calibration file...)
under References: HDTV-Rec 709 is setled
show gamma
and under Argyll Sensor... (new open field for the display section)
Argyll Meter Property Page: here it looks to me that there are some trouble with the depending work files which seems not to work correct any longer:
Display Type: the drop down field does not include anything, just blank area...
Reading Type: contact
Spectral sample: blank drop down field, nothing there to choose....

??
just wiped it out of the system again
installed it again
used english language
same thing as above
