<![CDATA[After using cx_Freeze - App can not be launched]]>Hi,

I have app made from python and QML/QtQuick. I used cx_Freeze to have a an executable file. Then I can run my app.exe on my PC, but on another (almost clean win 10 installation) it show this kind of error:
Please any advice how to fix that?
Thank you very much.

The tool is basically a wrapper around Nuitka for PySide6 deployment.

The documentation isn't published yet, but here is how you use it https://codereview.qt-project.org/c/pyside/pyside-setup/+/450121/11/sources/pyside6/doc/deployment/deployment-pyside6-deploy.rst

I had to install Visual Build Tool : see picture:
Then I can run my exe version of application builded by cx_Freeze. Would be nice if cx_Freeze could do it itself...

nuitka main.py --standalone

The "Shiboken" mentioned in the error message is the "glue" code which makes PySide6/Python work with Qt. Somehow I think the cx_freeze is not picking up all of its files/dependencies. That's all I know, I don't know exactly which bits of it cannot be found.

Nuitka

Ok I will try, and do you have any idea what dependenices could missing? Then I woul install it manually...

I would say that not all required dependencies have been deployed. You might want to test other tools like Nuitka.
