Hi @Apoorv Srivastava,
If you have repeated installation many times, please try to do a clean uninstall and re-install.
Please follow the below steps to remove all components of previous installed SQL Server completely:
1. Remove all SQL Server components from 'Programs and Features'
2. Backup the registry
3. Delete the following keys in 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
- Reboot the machine
In addition, please use an administrator account to reinstall SQL Server on your computer(Right click->run as administrator).
Regards,
Zoe Hui
