<div>I would like to thank everyone for their advice. It looks like the problem has been resolved and that it was not related to the fact that the rview.exe application does not come with the version of Radiance I am using (MinGW Radiance Installer for Windows (HEAD snapshot 2008-04-17) available for download at <a href="http://www.radiance-online.org/">http://www.radiance-online.org/</a>).</div>

<div>I had to reset my Radiance directory within the 'image viewer' program in order to be able to apply any of the overlays. Below is an excerpt from an NRC document explaining how to get started with Ecotect-Radiance-DAYSIM (available at <a href="http://irc.nrc-cnrc.gc.ca/ie/lighting/daylight/daysim_e.html">http://irc.nrc-cnrc.gc.ca/ie/lighting/daylight/daysim_e.html</a>), in which specific reference is made to the issue I experienced:</div>

<div></div>
<div>Please note: The first time you are trying to generate a falsecolor image you might get an error message stating "RGBE read error". If this is the case, you have to reset your Radiance directory within the 'image viewer' program above under OPTIONS >> SETTINGS (see also Step 30.a).</div>
<div></div>

<div></div>
<div>The NRC document describes how to import/export files from Ecotect/Radiance/DAYSIM. It is very helpful, although parts of it may be slightly outdated. For example, I think that the link provided for the Radiance download (<a href="http://www.arch.mcgill.ca/prof/reinhart/software/Radiance3P7forWindows.zip">http://www.arch.mcgill.ca/prof/reinhart/software/Radiance3P7forWindows.zip</a>) may refer to an older version of Radiance.</div>

<div></div>
<div>I am keeping my fingers crossed things will run smoothly from now on!</div>

<div>> Square One/AutoDesk recommends using Ecotect with Desktop Radiance. It is old, but if it is still available, it will resolve these issues. Their instructions--I hope they still work--are here: <<a href="http://squ1.org/wiki/Installing_Radiance_Tutorial">http://squ1.org/wiki/Installing_Radiance_Tutorial</a>>. If you want to use a more current Radiance, try copying "rvu" to "rview"; it is unlikely that you have "vi" on your Windows system to create a name conflict.</div>

<div>>> Hi,</div>
<div>>></div>
<div>>> I have just uninstalled Desktop Radiance and installed the MinGW version on my computer (Windows OS). I have been informed that this is the latest version of Radiance for Windows OS. Unfortunately I now have trouble reading images exported from Ecotect.</div>
<div>>> When I export the Ecotect example file "RADIANCE_example.eco" I am able to see a rendered view of the space in the image viewer, but I cannot run any of the options for the information overlay (e.g. contour lines, false color, daylight factors etc.) and get the message "RGBE read error"</div>
<div>>></div>
<div>>> When exporting the file from Ecotect, I noticed that when checking whether Radiance is functional, the exporter returned a message saying that the application "rview" is missing from the directory. Could this be the problem? If so, what are alternative ways for evaluating the radiance image?</div>
<div>>></div>
<div>>> I have uploaded an image of the error message to the Autodesk discussion forum:</div>
