I am making a self extract and running installer. It works, but there is a time gap between the exit of the progress bar of the extraction and the appearance of the main window. The process of the executable has already started, it just the GUI hasn't popped up yet.
I guess I can make another loading screen for my program, but since we already have a loading box from 7z I want to make use of it. Is there a way to tell 7z that the finish line is when the window pop up?
