V10 - Ribbon creation is not working

I can not create a Ribbon. I already tested with the example that is in developers.primaverabss and github (which are different) and none of them creates the Ribbon.

public class ConstroiRibbon : Plataforma
{
// exemplo no evento DepoisDeCriarMenus
    public ConstroiRibbon()
    {
        PSO.Dialogos.MostraAviso("Entrou aqui");
    }

    const string cIDTAB = "10000";
    const string cIDGROUP = "100001";
    const string cIDBUTTON1 = "1000011";
    const string cIDBUTTON2 = "1000012";

    private StdBSPRibbon RibbonEvents;
    /// <summary>
    /// This event will execute for all ribbon changes.
    /// </summary>
    /// <param name="e"></param>
    public override void DepoisDeCriarMenus(ExtensibilityEventArgs e)
    {
        // Register the Ribbon events.
        RibbonEvents = this.PSO.Ribbon;
        RibbonEvents.Executa += RibbonEvents_Executa;
        // Create a new TAB.
        this.PSO.Ribbon.CriaRibbonTab("Ferreira & Sanches", cIDTAB, 10);

        // Create a new Group.
        this.PSO.Ribbon.CriaRibbonGroup(cIDTAB, "Modulo FS", cIDGROUP);
        // Create a new 32x32 Button.
        this.PSO.Ribbon.CriaRibbonButton(cIDTAB, cIDGROUP, cIDBUTTON1, "FS Button", true, FSRibbon.Properties.Resources.LogoFS);
        this.PSO.Ribbon.CriaRibbonButton(cIDTAB, cIDGROUP, cIDBUTTON2, "Primavera Button", true, FSRibbon.Properties.Resources.Wallpaper_PBSS_9_1920x1080_16_9);
    }

            }
        }
        catch (System.Exception ex)
        {
            PSO.Dialogos.MostraAviso("Fail to execute the command.", StdBSTipos.IconId.PRI_Informativo, ex.Message);
        }
    }
}
