title: How to update Qt Maintenance Tool
body: <p>I am using Qt 5.10.1 on windows 10, when I was trying to add qt repositories using the Maintenance Tool, specifically I need to add the Qt Charts module. Then it gave me this error:</p>
  
  <blockquote>
    <p>Your Maintenance Tool appears to be older than 3.0.2. Please update it first to get access to new Qt packages.</p>
  </blockquote>
  
  <p>Why would this happen? I am currently using the latest Qt version, and I did not find a way to update the Maintenance Tool. How can I solve this problem? </p>
