This might be useful, refer to the following site:
http://irc.nrc-cnrc.gc.ca/ie/lighting/daylight/daysim_e.html

On the right under the Column click on the 'Getting Started' PDF link.

Navigate to page 26 (headed Radiance), steps 27-37 provide a walk through of how Ecotect exports to Radiance and the built in Radiance viewer that comes with Ecotct to create false-color images.

Step 37 'Info' box describes the RGBE error and suggests a possible way to fix it.

Step 30a shows the procedure to set-up Ecotect to export to Radiance and how to point to correct directory.
