Gilles, this is the general Radiance list. You probably want to post 
your errors and questions regarding Desktop Radiance to the Desktop 
Radiance list, for you're much more likely to get the help you're 
looking for.

In my experience Radiance works better as a 'full' version running 
under some form of Unix. I use it primarily with Cygwin on Windows.

Cygwin is a 'mini-Linux' that allows you to run some Linux tools under 
windows, and to port others to be able to run. It's open source, like 
Radiance, so it's free. Thankfully, Francesco Anselmo ported Radiance 
3.5 to run under Cygwin, which gives you full Radiance abilities under 
windows. Here's the links to both:

However there will be more of a learning curve for you with this 
approach, for you'll have to learn BASH Unix command-line tools as 
well as Radiance. I've also used Radiance with Mandrake Linux & OS X, 
and both worked very well. However, learning how to use the full 
Radiance package on Unix/Linux/Cygwin has taken me a long time, and 
I've got quite a ways to go. It's not the easy road, but by far the 
most rewarding. :-)

Also there is a commercial Radiance port for Windows called 'rayfront' 
that gives you a much easier to use interface for Radiance. This might 
be your best option off all, if Desktop Radiance doesn't work for what 
you need and you find the full command-line Radiance too daunting but 
you still want to use Radiance:

good luck!
