Hi @CELINE KUAN XIN YI
Please go to SQL Server Setup program (setup.exe) from SQL Server installation media-> Maintenance in the left-hand navigation area-> Repair.
If this doesn't work, you can uninstall it cleanly and reinstall it.
Please follow the below steps to remove all components of previous installed SQL Server completely:
- Remove all SQL Server components from 'Programs and Features'
- Backup the registry
- Delete the following keys in regedit:
--HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server
--HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSSQLServer
- Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall and delete all the sub-keys referencing SQL Server
- Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services and delete all the keys referencing SQL Server
- Reboot the machine
In addition, please use an administrator account to reinstall SQL Server on your computer (Right click->run as administrator).
You'd better disable your anti-virus software and firewall before installation. Also, it is recommended that you install in the default location.
Best regards,
