Hi @Vibin

Found that you have many instances installed, you should consider remove them clearly and try again.

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.

Besides, here is a link to an article that can help you to clean up properly: How to Uninstall SQL Server: A Step-by-Step Guide.
