Embeded

I can’t figure out why my fonts won’t be embeded. Any clue?

var tField:TextField = new TextField();
    var textFormat:TextFormat = new TextFormat();
    
    textFormat.font = "Avenir 45 Book";
    textFormat.size = 16;
    textFormat.color = 0xFFFFFF;
    tField.embedFonts = true;
    
    tField.defaultTextFormat = textFormat;
    tField.width = 200;
    //tField.embedFonts = true;
    
    //tField.autoSize = TextFieldAutoSize.LEFT;
    tField.text = textForField;
    trace(tField.textWidth);
