  <p>In ThisAddIn working with ribbon like this:</p>
  
  <pre><code>public partial class ThisAddIn
  {
      private void ThisAddIn_Startup(object sender, EventArgs e)

      {
          var pricelistRibbon = new PricelistRibbon();
          pricelistRibbon.ClickButtonRibben += PricelistRibbonOnClickButtonRibben;
          return pricelistRibbon;
      }
  
      private void PricelistRibbonOnClickButtonRibben(object sender, EventArgs eventArgs)
      {
          var control = sender as Office.IRibbonControl;
          if (control == null) return;
          try

              {

                      CreateSpecification();
                      break;
                  //..............

          {

  <p>Next I deploys this addin via ClickOnce. Installed MS Office 2007. Addin deployed successfully. In the settings you can see that Excel addin installed but not visible on the tape my TabControl.
  If I create a Ribbon (Visual Designer) instead of the Ribbon (xml) when the tape appears TabControl. How can I fix it?</p>
