I've tried everything and I can not solve a problem.</p>
  
  <p>Follow html:</p>
  
  <pre><code>&lt;div style="width: 800px; height: 500px;"&gt;
      &lt;iframe width="800" height="500" id="iframePdfViewer" seamless="seamless" scrolling="no" src="~/Scripts/pdfjs-dist/web/viewer.html"&gt;&lt;/iframe&gt;
  &lt;/div&gt;
  </code></pre>

  <p>And I also get a lot of warnings from l10n.js. I downloaded it here: <a href="http://mozilla.github.io/pdf.js/" rel="noreferrer">http://mozilla.github.io/pdf.js/</a> by clicking the "download" button.</p>
  
  <p>Any solution ?</p>
