IIS doesn't understand Atlas files with '.less' extension

[Diego_Bosca_Tomas (Diego Boscá Tomás)]

I’m trying to load Atlas into a IIS (just installed, fresh configuration). However, Atlas starts running but throws these errors when dealing with files with ‘.less’ extension.

I’ve tried to add the extension to the allowed mime types as text/plain, but doesn’t seem to work either. Anyone knows what else needs to be configured?

edit: files do exist in that path

Set the mime type to text/css. I am running IIS locally to serve the atlas resources, and that is how I have it configured.
