Comodo - Update

Good morning. I apologize for my bad engrlish.
Yesterday I installed Comodo Firewall Pro (Spanish language,because I’m Italian). I think it,s very ok, but this morning , on the actualizacion answered: Error 106.
The uncompleted update is due to using Firefox instead IE.
Please, how may I chose IE in actualizacion ? Thanks

Open Firefox, click Tools → Options → Main. At the bottom of the window, uncheck: “Always check to see if Firefox is the default browser on startup”, click OK and run the Comodo updater.
