Hi @Guerrero Aguila ,

Do you have any error messages to report. If so, you can post it. In order to solve your problem more efficiently, you need to add more details to your problem.

Also, here is a step by step to uninstall a clean SQL Server. I'll put it here first.

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
6. Reboot the machine

If you want to install it again, please use an administrator account to reinstall SQL Server on your computer(Right click->run as administrator).

Best regards,

Seeya
