Delete the install folder and reinstall the application with the installer.
If that not helps, go to the installation folder, open a terminal (cmd) and run urh_debug.exe and post the output.

Just tested latest master in a Windows 10 VM and it works fine there. Maybe this is some

Run as administrator
disable Windows Defender
cleanup registry

voodoo?

MrBambix · 2020-04-23T16:32:31Z

hi Tried running as admin for both installation and running for the regular and debug version. No difference really weird this. Reinstalled my whole php toolchain still no difference. This is an interesting problem 😁 Greetings Leo Verstuurd vanaf mijn iPhone

Are you able to run a simple hello world PyQt5 script like the following?

# https://pythonprogramminglanguage.com/pyqt5-hello-world/
import sys
from PyQt5 import QtCore, QtWidgets
from PyQt5.QtWidgets import QMainWindow, QLabel, QGridLayout, QWidget
from PyQt5.QtCore import QSize    

class HelloWindow(QMainWindow):
    def __init__(self):
        QMainWindow.__init__(self)

        self.setMinimumSize(QSize(640, 480))    
        self.setWindowTitle("Hello world - pythonprogramminglanguage.com") 

        centralWidget = QWidget(self)          
        self.setCentralWidget(centralWidget)   

        gridLayout = QGridLayout(self)     
        centralWidget.setLayout(gridLayout)  

        title = QLabel("Hello World from PyQt", self) 
        title.setAlignment(QtCore.Qt.AlignCenter) 
        gridLayout.addWidget(title, 0, 0)

if __name__ == "__main__":
    app = QtWidgets.QApplication(sys.argv)
    mainWin = HelloWindow()
    mainWin.show()
    sys.exit( app.exec_() )

Hi,

Nope same problem not showing the window, its getting weirder...

Ok, so there seems to be problem with your PyQt installation. Please run this:

python -m pip install --upgrade pip
python -m pip install --upgrade pyqt5

and see if it helps.

Hi,

No still nothing, i did however still have a php2.7 installatation on my pc which i just removed. Also uninstalled and reinstalled pyqt5 but still nope.. damn. Maybe some stuff from 2.7 stayed behind somewhere?

greetings,
Leo

That is probably unrelated, as a Python3 process will not use any libs from Python2 (except there is some weird naming convention on Windows).

Having said that, I am running out of ideas what could cause this behaviour. On Linux you could strace the application. I just saw there is also an strace for cygwin, so you could install cygwin and try.

Nevertheless, this appears to be a problem with PyQt5 itself as the hello world example is also not working. Therefore, you may be better off asking the PyQt5 developers for help.

MrBambix · 2020-04-24T05:02:37Z

Hi Johannes Thanks for all your help I will ask in the qt5 forum and post an update here. Greetings Leo Verstuurd vanaf mijn iPhone

It appears so! Did you get some reply in the Qt forums?

Hi Johannes, After a great session on the #pyqt IRC channel it was discovered that it is a bug in the QT release currently in URH. When we rolled it back all started working just fine. So now URH is running here with Qt5Core 5.14.10 Regards Leo Van: Johannes Pohl <[email protected]> Verzonden: Thursday, 23 April 2020 22:27 Aan: jopohl/urh <[email protected]> CC: MrBambix <[email protected]>; Author <[email protected]> Onderwerp: Re: [jopohl/urh] On Windows 10 UI does not render, executable is running though (#769) That is probably unrelated, as a Python3 process will not use any libs from Python2 (except there is some weird naming convention on Windows).

Mhh so PyQt5 5.14.2 is completely bugged (i.e. not usable) on Windows 10? Is there an official bug report about it?

MrBambix · 2020-04-25T17:36:34Z

Hi Johannes Yes it is. No not yet they didn't have the time to get a full debug running on my laptop. They said maybe the will log the issue regardless. Maybe you can work together with them on the freenode #pyqt IRC channel. Greetings Leo Verstuurd vanaf mijn iPhone

I was interested whether this is a general problem on Windows 10 or not. However, in my VM I cannot reproduce this behaviour so I will not exclude PyQt5.12 from URH dependencies in general. I will close here and I am glad your problem is solved!
