Pyinstaller setting icons don't change

I know this is old and whatnot (and not exactly sure if it's a question), but after searching, I had success with this command for --onefile:

pyinstaller.exe --onefile --windowed --icon=app.ico app.py

Google led me to this page while I was searching for an answer on how to set an icon for my .exe, so maybe it will help someone else.

The information here was found at this site: https://mborgerson.com/creating-an-executable-from-a-python-script

I think this might have something to do with caching (possibly in Windows Explorer). I was having the old PyInstaller icon show up in a few places too, but when I copied the exe somewhere else, all the old icons were gone.

The below command can set the icon on an executable file.

Remember the ".ico" file should present in the place of the path given in "Path_of_.ico_file".

pyinstaller.exe --onefile --windowed --icon="Path_of_.ico_file" app.py

For example:

If the app.py file is present in the current directory and app.ico is present inside the Images folder within the current directory.

Then the command should be as below. The final executable file will be generated inside the dist folder

pyinstaller.exe --onefile --windowed --icon=Images\app.ico app.py
