Ugg, filthy, it's so long since I have had to use it I didn't recall. There are 
better visual gamma pre-set (LUT) and adjustment programs and the test patch 
used to gauge Gamma in the Adobe tool is very poor and leads to errors.

The targets on this page being some of the best (3 point linearity and 
graypoint across various system gammas):

And this little tool will successfully obviate the need for the Adobe gamma 
tool and can be used to linearize Windows systems without PS loaded:
