Why is OllamaSetup.exe so large

I also tried downloading [ollama-windows-arm64.zip](https://github.com/ollama/ollama/releases/download/v0.5.1/ollama-windows-arm64.zip) and replacing some files in my user folder which doesn' t fix the tray icon still notify the update. Could there be a smaller OllamaSetup.exe ? This combined with the tray "restart to update" button not effective can be very annoying.
