Cannot generate grid based simulation Analysis Recipe

it only showed a wrong message as

“1. Solution exception:Access to the path ‘C:\Users\’ is denied.”

Any idea to solve this kind of issue? I am using a school computer to run grasshopper instead of my own tower.

Looks like the sky file is created in c:\users which is not a place that the component can have access. If you connect a different path to Ladybug_Ladybug component the default directory will change and then the sky files will be written to the same directory. That should solve your problem.
