    Hi! You must disable Smart App Control to install the app. Microsoft does not provide ways to bypass Smart App Control protection for individual applications. It recommends that you contact the app developer and encourage them to sign the app with a valid subscription.

    To disable Smart App Control, open Windows Settings > Privacy & Security > Windows Security > Apps & Browser control > Smart App Control > Off.

    WARNING: You cannot enable Smart App Control after uninstalling it. To enable it again, you need to reinstall Windows. Don't worry, Windows Defender will continue to function.

    To unblock a file that has been blocked by Smart App Control, you can use the Unblock-File cmdlet in PowerShell. Here’s how you can do it:

    1. Open PowerShell: Search for PowerShell in the Start menu and run it as an administrator.
    2. Use the Unblock-File cmdlet: Execute the following command, replacing C:\path\to\your\file.iso with the actual path to your Corel installation file: 
         Unblock-File -Path "C:\path\to\your\file.iso"

    This command will remove the block on the file, allowing you to open it. Make sure to verify that the file is safe before unblocking it.

    If Smart App Control is still preventing you from running the file, you may need to check its settings in Windows Security under App and Browser Control to see if it is in enforcement mode.
