    Hi Roberto Filippi,

    Thank you for posting in the Q&A Forums.

    When you encounter a problem installing SQL Server 2022, specifically the SQL database engine not being able to start, there can be several reasons. Here are some common causes and corresponding troubleshooting steps in English for your reference:

    1. Service not started or incorrectly configured:
      • Open the Windows Services Manager (by running services.msc command), locate the SQL Server (MSSQLSERVER) service.
      • Check if the service is running, if not, try to start it manually.
      • Right-click the service, select "Properties," and in the "General" tab, ensure that the "Startup type" is set to "Automatic."
    2. Port conflict:
      • SQL Server requires the use of a specific port (default is 1433), and if that port is being used by another application, it can cause startup failure.
      • Check and ensure that the port required by SQL Server is not being used by another program.
    3. Configuration error:
      • Examine the configuration files of SQL Server, including database file paths, log file paths, port settings, etc., to ensure they are consistent with actual conditions.
    4. Hardware or resource issues:
      • Check if the server hardware is working properly, such as sufficient hard disk space and normal memory.
      • Ensure that the system resources required for SQL Server's operation (such as memory, disk space, etc.) are adequate.
    5. Analyze log files:
      • SQL Server generates detailed log files during operation, which are usually located in the log folder of the installation directory.
      • When a startup failure occurs, examine these log files to obtain specific error messages. Detailed analysis of the logs can quickly identify the root cause of the startup failure.
    6. Database file corruption or permission issues:
      • If the database files are corrupted, it may cause SQL Server to fail to start. Try recreating the database or restoring a backup file.
      • Check the permission settings of the database files to ensure that the SQL Server process has sufficient permissions to access these files.
    7. Version incompatibility:
      • If the SQL Server version is incompatible with the operating system or other installed software, it may cause startup issues.
      • Try upgrading the SQL Server version or installing an operating system and software compatible with SQL Server.
    8. Security software blocking:
      • Some security software may prevent SQL Server from running. Try temporarily disabling or configuring the security software to allow SQL Server to run.
    9. Ultimate strategy:
      • If none of the above methods solve the problem, consider reinstalling SQL Server. Before reinstalling, ensure to back up important database files and configuration files to prevent data loss.

    Best regards
