Could not find QtWebEngineProcess.exe

when running :

from PySide2.QtWebEngineWidgets import *

I get the following error:

"Could not find QtWebEngineProcess.exe"

I'm using the CI's wheel : "PySide2-5.9.0a1-5.9.5-cp36-cp36m-win_amd64.whl" from 03/09/2018

"QtWebEngineProcess.exe" does exists in the following location but isn't detected for some reason:

C:\Python36\Lib\site-packages\PySide2\QtWebEngineProcess.exe

I moved "QtWebEngineProcess.exe" to Python's root folder:

C:\Python36\QtWebEngineProcess.exe

This fixes my import however my "QWebEngineView" displays a "blank" / white page instead of my html.

I installed the wheel using "pip install PySide2-5.9.0a1-5.9.5-cp36-cp36m-win_amd64.whl" on a Windows 10 machine.

I didn't have the issue with my custom compiled version of PySide2 from a few months back.

Is this a deployment problem ?

Thanks.

UPDATE:

Copying the following files to C:\Python36 (python's root folder) seems to be a workaround

C:\Python36\qtwebengine_devtools_resources.pak
C:\Python36\qtwebengine_resources.pak
C:\Python36\qtwebengine_resources_100p.pak
C:\Python36\qtwebengine_resources_200p.pak
C:\Python36\QtWebEngineProcess.exe
