I don’t speak Spanish, but Schematic, PCB, etc is all in Spanish. Tried removing and downloading new V9.04. Same problem. Help!
Somewhere in your system there is a kicad_common.json file.
Open this with a text editor, search for "language": and change to "language": "English",
Save the file and then start KiCad.
The language can be selected in the menu, in the menu Preferences - set Language, do not use the default value, select the appropriate language
