Windows Installation
If Microsoft Defender SmartScreen warns that 4SCREEN isn't commonly downloaded, this is expected for a new application.
- Download 4SCREEN from the official website.
- If Edge blocks the download:
- Open Edge Settings.
- Go to Privacy, Search, and Services.
- Scroll to Security.
- Temporarily disable Microsoft Defender SmartScreen.
- Download the installer again.
- Run the installer.
- Turn SmartScreen back on after installation.
This warning occurs because 4SCREEN is a new application and has not yet built Microsoft's download reputation.
