Hi

However I have already use radiance without any problem but

today An error message comes up when I run Radiance

Invalid or absent registry key - HKEY_CURRENT_USER\SOFTWARE\Lawrence
Berkeley National Laboratory\Desktop Radiance

after that when I click OK under this message ,another message ...

However I installed lamps in a model and run the Apache Sensor Calculation in Radiance and selected the radiance link in apachesim.The total light energy has remained zero. What's the problem in this process?
What should I do to get total light Energy for a model?
