Issues with annual daylight and grid based analyses

Hey guys,
Issue1) grid-based analyses work based on CIE standard sky but is not working based on the climate-based sky and provides the following error:

  1. Solution exception:Failed to read the results!
    fatal - cannot find function file “”

Issue2) Annual daylight analyses is working properly when the epw file is connected to it but does not provide any result.

I have installed DAYSIM 4, Radiance 5.1 exactly as instructed and I am using Rhino 6. The only thing that is not installed is Python I guess.

Thx in advance!

Do you find in your Radiance installaton which should be at C:\Radiance\lib


Thx @devang for your answer, yes it does, it exists there but still not working!
