I was building an application(Equation solver) in PyQt5 which contains two frames. The first frame works just fine but the 2nd frame contains a QWebEngine widget which worked fine when I directly ran it from the code in my code editor but when I converted into an .exe file using cx_freeze, on running the second frame I get an error saying "Could not find QtWebEngineProcess.exe" .

I did a little bit of digging myself and found out that its quite common actually, even found a question similar to this in stack overflow : here. I tried adding the qt.conf file but to no avail, the error still persists.

I am at a loss here, been working on this for so long and now this error really ruined the flow. I would be very grateful for any kind of help. Thanks.

  • I am having the same problem when freezing my project using PyInstaller. I am using Python 3.10.7, PyQt 5.15.7, PyInstaller 5.6, and PyQtWebEngine 5.15.6. I using LInux: Ubuntu 22.10. I have also tried creating a qt.conf file as suggested elsewhere, but have had no luck. – trinkner Oct 25 '22 at 18:43
