Overcoming SQL Server 2012 Installation Error 0x84B70001

Navigate the error code 0x84B70001 during SQL Server 2012 setup with the following effective solutions:

1. Verify System Compatibility: Ensure your hardware matches SQL Server 2012's specifications. Confirm operating system, processor specs, RAM, and available storage against the official requirements.
2. Suspend Antivirus Programs: Temporarily deactivate antivirus software to prevent interference during the SQL Server installation process.
3. Administer Setup with Elevated Privileges: Right-click the SQL Server setup file and choose 'Run as administrator' to obtain the necessary system permissions for installation.
4. Update Windows: Ensure your system is fully updated. Install all pending Windows updates and reboot your machine prior to the SQL Server installation.
5. Initiate a Clean System Start: To avoid software conflicts, perform a clean boot by configuring the System Configuration to 'Selective startup' and deselecting all options except 'Load system services.'
6. Mend .NET Framework: Since SQL Server 2012 relies on .NET Framework 3.5 or newer, repair or reinstall this framework if problems arise during installation.
7. Remove Older SQL Server Editions: Uninstall any previous SQL Server installations to prevent conflicts with the new installation.
8. Examine Installation Media: Inspect your DVD or USB drive for physical damage if using physical media for installation. Alternatively, copy the setup files to another location and attempt installation from there.
