Unfortunately 'falsecolor' (which is the master tool behind most
of these overlays) is not distributed with the MinGW binaries
because it is a CSH-script that does not run on Windows. Therefore
the ImageViewer bundled with Ecotect can not generate this type
of analysis.

There is another picture viewer around which is based on
Python and that seems to be the best option to create
falsecolor images on Windows at the moment:

Raddisplay - http://www.deluminaelab.com/en/tools.html

It requires some time to setup, though.

The application 'rview' is now called 'rvu' and AFAIK it has
not been ported to Windows.


There have been some significant changes to the Radiance
applications since Desktop Radiance has been released. This
affects mostly the rendering process, though. The image format
is still the same and you should be able to open a 'new'
image in the old 'rview'. You could try to copy the missing
applications from your DR installation over to the MinGW
installation and see if that solves your problem.
