title: Pyinstaller: Could not find QtWebEngineProcess.exe for PyQT5 Web Application
body: <p>I am developing a web application which displays a folium map. The web app has 3 tabs and each tab has a <strong>QtWebEngineView</strong> widget added into them.</p>
  <p>I am trying to create a standalone .exe file for my web application. So I have used Pyinstaller to convert my project into a single .exe file. I already had to make some changes in my spec file to solve a previous issue (fixed). This is how the spec file looks</p>

  <p>On running <code>Pyinstaller mainspec</code>, the dist folder and main.exe file is created but once I run the the main.exe file, I am getting this error:</p>
  <pre><code>Could not find QtWebEngineProcess.exe
  </code></pre>
  <p>I have tried reading through the Qt Documentation for deploying Qt WebEngine Applications and noticed that</p>
  <blockquote>
  <p>The WebEngine process is executed for each QWebEngineView or
  WebEngineView instance</p>
  </blockquote>
  <p>I am not sure, where I have to make a modification or correction. Can someone help me out with this?</p>
