Answer 1

Please ignore the post from Yufeishao. Or at least the part where he/she suggests that you should uninstall and fiddle in the registry.

The error means that Setup was not able to access SQL Server when Setup wanted to run install scripts. You should check the file C:\Program Files\Microsoft SQL Server\MSSQL15.MSSQLSERVER\MSSQL\LOG\ERRORLOG (assuming a default installation) to find out why. Once we know why SQL Server starts we can look into how to repair this.

Hi @MAYUR U ，

Uninstall SQL Server completely from add remove program：

1. Uninstall the existing SQL Server and all the components from the add remove program.
2. Backup the registry.
3. Delete the following keys using regedit:
   --HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server
   --HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSSQLServer
4. Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall and delete all the sub-keys referencing SQL Server.
5. Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services and delete all the keys referencing SQL Server.
6. Rename all the SQL Server folders in the computer.
7. Reboot the machine.

and then reinstall sql server, if you still get the error, please check your error log(Program Files\Microsoft SQL Server\MSSQL.n\MSSQL\LOG\ERRORLOG and ERRORLOG.n files.)
