Downloaded free trial but the software is in two languages?

The bar menu is in French but the left menu is all in English. Can you tell me how to change it.
I want everything to be in French and changed the settings accordingly but the left menu remains in English.
Thanks for your help

If by left menu you mean the Binder - the list of files and folders in the Project - then these are created from templates with folder names that are in English. The documents can be renamed if you wish. Just double-click on them to edit the names.
