<p class="MsoNormal">Hello All,</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have built (with commercial license) PyQt5 for python 2.7. I used VS 2015 and packaged my build with what I believe to be the appropriate windows redistributables.</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">With the resulting build I have had success getting it to run on an independent (i.e. not the build machine) Windows 8.1 machine.
</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">However when attempting to get it to run on a Windows 10 I have run into the dreaded:</p>
<p class="MsoNormal">This application failed to start because it could not find or load the Qt platform plugin “windows”</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">This is usually a sign that the qt.conf is bad but why would it work on Windows 8 but not Windows 10? Furthermore it does not work even if I put a qt.conf file right next to the python.exe.</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have followed the file structure used by Phil in the Python 3 version of PyQt5 (e.g. PyQt5\Qt\bin and PyQt5\plugins, etc) and modified the __init__.py file to set various environment variables. Like this:</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">import os<o:p></o:p></p>
<p class="MsoNormal">import sys<o:p></o:p></p>
<p class="MsoNormal">dir_name = os.path.dirname(__file__)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">_path = os.path.dirname(__file__) + '\\Qt\\bin;' + os.environ['PATH']<o:p></o:p></p>
<p class="MsoNormal">os.environ['PATH'] = _path<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">os.environ['QML_IMPORT_PATH'] = os.path.join(dir_name, 'Qt', 'qml')<o:p></o:p></p>
<p class="MsoNormal">os.environ['QML2_IMPORT_PATH'] = os.path.join(dir_name, 'Qt', 'qml')<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">os.environ['QT_PLUGIN_PATH'] = os.path.join(dir_name, 'Qt', 'plugins')<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">os.environ['QT_QPA_PLATFORM_PLUGIN_PATH'] = os.path.join(dir_name, 'Qt', 'plugins', 'platforms')</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">However the message persists.</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">As I said, it works on independent Windows 8.1 machines but not with Windows 10. Does anyone have any tips or experience or success with PyQt5 for python 2.7 on Windows 10?</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">With respect,</p>
<p class="MsoNormal">Nathan<o:p></o:p></p>
