Block mesh not running 2.0

Hi guys, I’m new in this community. I’ve been searching for an issue I have in Butterfly and I found this old post: Block Mesh not running where sadly there aren’t so many replies. I’m encountering the same problem as he described, in particular when I run the “2.1 Blockmesh” component of the file “01_0_outdoor_airflow” I get this error message:

Updating cell size in blockMeshDict.
Updating grading in blockMeshDict.
Saved changes to blockMeshDict to:
Runtime error (Win32Exception): WindowsError

line 232, in run, “C:\Users\loren\AppData\Roaming\McNeel\Rhinoceros\6.0\scripts\butterfly\”
line 756, in command, “C:\Users\loren\AppData\Roaming\McNeel\Rhinoceros\6.0\scripts\butterfly\”
line 788, in blockMesh, “C:\Users\loren\AppData\Roaming\McNeel\Rhinoceros\6.0\scripts\butterfly\”
line 52, in script

I followed the instructions and I’m running both rhino and blueCFD as administrator.
Thanks for the help!
