Resolving SQL Server 2017 Installation Error 0x800F0906

There are multiple approaches to troubleshoot the error code 0x800F0906 during SQL Server 2017 setup:

1. Enable .NET Framework 3.5: If your system lacks .NET Framework 3.5, you may encounter this error. Navigate to Control Panel > Programs and Features > Turn Windows features on or off, select .NET Framework 3.5 (includes .NET 2.0 and 3.0), and click OK to install.
2. Pause antivirus protection: Occasionally, antivirus programs can disrupt the installation process. Consider pausing your antivirus temporarily and retry the setup.
3. Utilize physical or virtual media: Instead of installing from a downloaded file, use the original installation media. Either burn the ISO to a disc or mount it virtually, then execute the setup.exe file.
4. Verify system compatibility: Confirm that your computer meets the SQL Server 2017 requirements. Review both hardware and software prerequisites on the Microsoft website.
5. Execute setup with administrative rights: To ensure full access permissions during installation, right-click on the setup.exe file and choose 'Run as administrator.'
6. Ensure Windows Update is active: Verify that the Windows Update service is operational and current. Access it via Control Panel > Administrative Tools > Services > Windows Update and start it if necessary.
7. Initiate a clean system boot: To prevent software or service conflicts, perform a clean boot. Navigate to Start, type 'msconfig,' go to System Configuration, select Selective startup, uncheck Load startup items, click OK, and reboot your machine.
