Error in creating dif_1.mtx file for cumulative sky matrix

Hello,
I’ve downloaded the epw file of Milano-Linate and placed it in “RadiationAn” folder on my computer, I’ve defined the “RadiationAn” folder as directory. Once i’ve set True in the toggle i found the gendaymtx.exe file in that folder but I obtained this error.


I would like to understand how to solve it, I’m at the very first step of using the software so I’m sorry if it’s too common for the forum but I can’t figure it out.

Thank you very much
