Repair a Failed SQL Server 2012 Installation

Repair operation can be used in the following scenarios:

  • Repair an instance of SQL Server that is corrupted after it was successfully installed.

  • Repair an instance of SQL Server if the upgrade operation is cancelled or fails after the instance name is mapped to the newly-upgraded instance.

    • If you see the following message in the summary log, you can repair the failed upgrade instance:

      "SQL Server upgrade failed. To continue, investigate the reason for the failure, correct the problem, and then repair your installation."

    • If you see the following message in the summary log, you need to uninstall and reinstall SQL Server. You cannot repair the SQL Server instance.

      "SQL Server upgrade failed. To continue, investigate the reason for the failure, correct the problem."

When you repair an instance of SQL Server:

  • All missing or corrupt files are replaced.

  • All missing or corrupt registry keys are replaced.

  • All missing or invalid configuration values are set to default values.

Before you continue, for SQL Server failover clusters, review the following important information:
