I have iClone 6 and downloaded the trial for Indigo RT!
I just made a simple image with two avatar! Do the same
way as the tutorial! A photo of the head with camera
and then use Indigo lightning! Just tick the boxes and lower
the sun and change the angle from it! Export it to Indigo
for render! Now it has continue render for over 52 minutes in Indigo RT!
Is that normal?

More than 70 minutes have passed now and it still working! LOL
Does it never stop and finish?

Thanks Garry!
I begin to wonder, cause I thought it should stop by itself
then it was finished! it would be easier if it did so you
know you don't stop it to early!
I will stop it now!

You can set it to stop after a certain amount of time or a desired number of iterations.
So if experience with an image tells you it looks good after 380 iterations, you could set it to stop at 400 (a bit extra, just to be sure).

I don't have screenshots at the moment because I'm away from my main computer.

Enhanced answer... now with pictures! 

In iClone, you can specify a number is Samples Per Pixel ("iterations") or a time limit (in seconds) for each image.  You can only set that in iClone if you are doing an animation sequence.

For individual images, it is easy to set the limits in Indigo itself.  First you have to STOP (not pause) an existing render.  Then on the "Render" menu (on the right side of the screen in my setup) you can pick the drop-down menu to access "Render Settings."  There you can specify a Time (in seconds) or a SPP (Samples Per Pixel) at which to stop.  The "-1" indicates infinity.  If you set both Time and SPP values, it will stop at whichever limit it reaches first.

Please share a picture of your results.

Here is another test image I made today and after 30 minutes render it looks
like this! I turn of the iClone Directional light and only used Indigo sun!
I set the sun at midday and also position it more or less in front of the scene!
I guess it get dark cause of sky prop in the scene!

You can compare it to this render that is done
only with iClone6 and one Directional light!
