When I apply the main loop solution, I still have the same problem. The script works perfectly when running the .py script. So the exe is created with the nuitka, and when I run the exe the console opens for a few seconds, and then closes, but nothing happens. I also opened the exe using cmd, but it just completes without any output. Can someone try to create sample app and test this? Or maybe you already c the solution when looking at the code. You need a few pdf files and a XLS sheet in a folder called “Project Fluvius” on the user’s desktop.
