When I use the command:
pyinstaller.exe --icon=test.ico -F --noconsole test.py
All icons do not change to test.ico. Some icons remain as the pyinstaller's default icon.
Why?
All icon change in
Some remain default
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.
