Comment (by muellea):

 Thank you jef,
 now i have QtWebEngineProcess.exe, it's in my path, but python/Qt doesn't
 find it. So it's quite the same.

 I do use this little python script for further testing. It tries to show a
 QWebEngineView.

 {{{
 import sys

 from PyQt5.QtWidgets import QApplication
 from PyQt5.QtWidgets import QMainWindow
 from PyQt5.QtWebEngineWidgets import QWebEngineView
 from PyQt5.QtCore import QUrl
 def main():
     app = QApplication(sys.argv)
     window = QMainWindow()
     window.setWindowTitle('PyQt Demo')
     window.setGeometry(320, 180, 960, 540)
     view = QWebEngineView()
     view.load(QUrl('http://leafletjs.com/')) # error here
     window.setCentralWidget(view)
     window.show()
     sys.exit(app.exec_())
 if __name__ == '__main__':
     main()
 }}}

 QT_PLUGIN_PATH ist set. When I also set QTWEBENGINEPROCESS_PATH to the
 correct path, the error isn't showing -  but then i got new ones:

 {{{

 }}}

 It seems, qt has a wrong configuration, icudtl.dat is in
 G:\tmp\q3\apps\Qt5\resources, qtwebengine_locales is under
 G:\tmp\q3\apps\Qt5\translations. I used py3_env.bat and qt5_env.bat before
 execution.

 My path:
 {{{
 PATH=G:\tmp\q3\apps\qt5\bin;G:\tmp\q3\apps\Python36;G:\tmp\q3\apps\Python36\Scripts;G:\tmp\q3\apps\qt5\bin;G:\tmp\q3\bin;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\system32\WBem;G:\tmp\q3\apps\Python36\Scripts;G:\tmp\q3\apps\qgis\bin
 }}}

 Some entries are doubled, as you can see...
