Check SQL Server Compatibility
Ensure the SQL Server version you are trying to install is compatible with Windows 11:
- SQL Server 2019 and SQL Server 2022 are fully supported on Windows 11.
- If you're using an older version (e.g., SQL Server 2016 or earlier), it might not be compatible.
- SQL Server setup generates detailed logs that can help pinpoint the issue:
- C:\Program Files\Microsoft SQL Server<Version>\Setup Bootstrap\Log
- Check System Requirements Verify that your system meets the minimum requirements for SQL Server:
- Processor: x64-compatible CPU
- RAM: At least 4 GB (8 GB or more recommended)
- Storage: At least 10 GB of free disk space
- Windows Features: Ensure .NET Framework 3.5 and 4.8 are installed/enabled.
- To enable .NET Framework:
- Go to Control Panel > Programs > Turn Windows features on or off.
- Check .NET Framework 3.5 and .NET Framework 4.8.
- Click OK and restart your computer if prompted.
- Temporarily disable antivirus or firewall software during the installation.
- Ensure no other database servers (e.g., MySQL, PostgreSQL) are running on conflicting ports (default is TCP 1433).
