Steps to Resolve Error Code 0x800F0906: SQL Server 2016 Installation Failed

Here are some alternative methods to resolve this error code:

1. Enable .NET Framework 3.5: This error might arise if the .NET Framework 3.5 is absent on your machine. Activate it by navigating to Control Panel > Programs and Features > Turn Windows features on or off > .NET Framework 3.5 (includes .NET 2.0 and 3.0).
2. Temporarily disable antivirus software: Occasionally, antivirus programs can disrupt the installation. Temporarily switch off your antivirus software and attempt to install SQL Server 2016 again.
3. Utilise the installation media: If you're installing SQL Server 2016 from a downloaded file, consider using the installation media instead. Write the ISO file to a DVD or USB drive and try installing from there.
4. Verify system requirements: Ensure your system meets the minimum specifications for installing SQL Server 2016. Check the Microsoft website for these requirements.
5. Execute the installation as an administrator: Right-click the installation file and choose 'Run as administrator'. This will grant the necessary permissions for the installation process to complete.
6. Review the installation log: The log may offer more insights into the error. Look for error messages in the log file and attempt to address them.
7. Perform a clean boot: Third-party software can sometimes obstruct the installation process. Try a clean boot of your system and then reinstall SQL Server 2016.
