So I'd first uninstall any previous gretl versions from the system and then reinstall gretl. Apart from that, the language in gretl is set via Tools (second menu), Settings or Preferences (don't remember in English, but it's the entry at the very bottom, then Main (first sub-entry) which opens a window, the first tab (General) has the language choice drop-down menu (third from bottom). Or you could start gretl from the command line with the option --english (I think). good luck, sven
