How can I fix the 'Unable to download installation files' error in Visual Studio Installer? (Theres no Internet issue)

You can try these steps to fix it:

3.      Check Proxy , VPN, or Firewall Settings

4.      Use the visual studio layout installer(offline mode)

If the installer keeps failing, you can download the full offline installer.
