title: Missing dll files when using pyinstaller
body: <p>Good day!</p>
  
  <p>I'm using python 3.5.2 with qt5, pyqt5 and sip14.8.
  I'm also using the latest pyinstaller bracnch (3.3.dev0+g501ad40).</p>
  
  <p>I'm trying to create an exe file for a basic hello world program.</p>
  
  <pre><code>from PyQt5 import QtWidgets
  import sys
  
  class newPingDialog(QtWidgets.QMainWindow):
  
  def __init__(self):
      super(newPingDialog, self).__init__()
      self.setGeometry(50, 50, 500, 300)
      self.setWindowTitle("hello!")
      self.show()
  
  
  app = QtWidgets.QApplication(sys.argv)
  GUI = newPingDialog()
  sys.exit(app.exec_())
  </code></pre>
  
  <p>At first, I used to get some errors regarding crt-msi. So I've reinstalled SDK and c++ runtime and added them to my environment.
  But now I keep getting errors about missing dlls (qsvg, Qt5PrintSupport)</p>

  <p>I've checked and both dlls exist and have their PATH set. I also tried to manually add them to my dist folder, but it didn't helped.</p>
  
  <p>I'll highly appreciate any advice you might have!</p>
