<h3 id="ricochetTor" class="anchor"><a href="#ricochetTor"><i class="fas fa-link anchor-icon"></i></a> Updating the Tor binary included with Ricochet</h3>

Currently there are no known vulnerabilities with Ricochet. The software is safe to use as long as you update the included Tor binary to the latest version.

<ol class="long-string-list">
  <li>Download the <a href="/browsers/#browser"><i class="fas fa-link"></i> Tor Browser</a>.</li>
  <li>Run the Tor Browser installer or extract package for your platform. Windows (.exe), MacOSX (.dmg) and Linux (.tar.bz2).</li>
  <li>Copy the Tor binary or create a symbolic link to it: </li>
  <br>
  <ul>
      <li><strong>Windows: </strong>Copy the Tor binary included with the Tor Browser and overwrite the old one included with Ricochet.</li>
      <ul>
          <li>Tor Browser binary: <code>%HOMEPATH%\Desktop\Tor Browser\Browser\TorBrowser\Tor\tor.exe</code></li>
          <li>Ricochet's included binary: <code>%HOMEPATH%\Desktop\Ricochet\tor.exe</code></li>
