Hello, Massimo. I believe that this is set by default based on the language pack you have installed with Inventor. For example, mine is installed by default in English. The Default CC files location is set out of the box. When I placed my very first component, the en-US folder was created. Was your Inventor installed using English as the default?
@johnsonshiue does this sound right?
