title: Pyinstaller Packed EXE failed to run script on other PC. says: Qt5Core,dll not found
body: <p>The produced app.exe from the code below starts OK on my PC, but failed to start on other computers (all windows 10). It can't run it because of fatal error. Failed to run script. The command line says: Qt5core.dll could not be found.
  I looked inside dist folder and the .dll file is there.</p>
  
  <p>I used very simple script that show only an empty form.</p>
  
  <pre class="lang-py prettyprint-override"><code>import sys
  from PyQt5.QtWidgets import QApplication, QWidget
  app = QApplication(sys.argv)
  window = QWidget()
  window.show()
  app.exec_()
  </code></pre>
  
  <p>Pyinstaller: 3.5
  PyQT5: 5.13</p>
  
  <p>What is the problem?</p>
