SQL instances still remain after uninstalling

Hi,
I carried out the uninstallation of SQL server on my computer including the instances. When I reinstall SQL server they keep appearing. How can I permanently remove them to reuse the default instance name?

You must have not uninstalled the SQL Server instance correctly. How did you remove it ?

Are you uninstalling the DB engine services also ? Can you post summary file generated post uninstall. This link should help you locate it. Look for the date when you uninstalled the file, Post content of that file.

Hi @alvaroarancibiap, are you trying to remove the 2 instances? or you would like to uninstall SQL server? If you are preparing to remove both of instances, I suggest that you can uninstall SQL server, and then reinstall a new SQL Server.

I followed the instructions in this link, and after cleaning the SQL server registry and changing the folder names, I tried to install a new instance. The following error message appeared during installation.

Hi @alvaroarancibiap,

Have you run setup.exe as administrator? The error code: 0x84BB0001 occurs under the following scenarios, so please make sure there have enough permissions to install SQL Server. You could get more details from this link.

  1. Remnants of previous failed SQL Server installations still exist on your computer.

  2. SQL Server installation is corrupted, you may need to download the SQL Server media again, and try install SQL Server again.

  3. The user did not have the permissions to access the register, you can grant full permissions to below registry keys to the setup account and SQL Service account.
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\120\


Best regards,
Carrin
