How to disable other toolbar in my custom xml ribbon in Excel using VSTO

Question

Here is a situation: I created my own ribbon for Office (Word, Excel, PowerPoint) with some buttons. Ribbon was created in C#, VSTO, XML (not Designer). So there is a new ribbon in all of these programs with a ribbon group where are my buttons. The only exception is Excel, where there is a "Custom Toolbar" group on 1st place and my group on 2nd. The best part is that this "Cutsom Toolbar" doesn't show up on every computer I installed my add-in. My question: how this "Custom Toolbar" show up on a new ribbon I created and is there any way to disable it? Ribbon code:

<?xml version="1.0" encoding="UTF-8"?>
<customUI xmlns="http://schemas.microsoft.com/office/2009/07/customui" onLoad="Ribbon_Load">
  <ribbon startFromScratch="false">
    <tabs>
      <tab idMso="TabAddIns" label="MyAddIn">
        <group id="GroupInclude" label="MyAddIn">
          <button id="saveMyAddIn" label="Save my file" getImage="imageButton" size="large"
             onAction="saveMyAddInButton" getEnabled="GetEnabled"
          />
          <button id="configurMyAddIn" label="MyAddIn Options" getImage="imageButton"
             onAction="configureMyAddInButton"
          />
          <button id="goToMyAddIn" label="Go to MyAddIn" getImage="imageButton"
             onAction="goToMyAddInButton"
          />
          <button id="aboutMyAddIn" label="About MyAddIn" getImage="imageButton"
             onAction="aboutMyAddInButton"
          />
        </group>
      </tab>
    </tabs>
  </ribbon>
</customUI>

If you see this "Custom Toolbar" in the Addins tab then you got another addin installed in the machine. You need to remove or disable it,

To disable Go to File => Options => Add-Ins tab => choose COM Add-ins in the Manage dropdown and click Go, you should all the addins that are loaded.

Removing the addin completely depends on what addin it is.
