I am trying to Install SQL Server 2019 Developer Edition in my personal laptop for some training purposes. But during installation, I keep getting the 0x851a0019 Could Not Find Database Engine Startup Handle error.

I have tried changing the SQL Server Database Services' account name to NT Authority/System as mentioned in the below Microsoft Blog, followed all the steps, but I still keep getting the same error. What additional steps do I need to do to make sure it installs fine?

    The problem is that the paths for the resource database and model are incorrect. They look like the paths from some build server in Redmond.

    I note that you have select a non-default location for your installation. I can't say whether this is the reason, but you could try a new install with a default location.

    Hi @Jashobanta Chakraborty ,

    You can also try to uninstall SQL Server and reinstall it.
    And before reinstall, 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
      Then right click on Setup.exe and select run as administrator.
      When you reach Server Configuration page where you select Service account please select Local System account(NT AUTHORITY\SYSTEM). After the installation is successful, you can choose another account to log in.

    Best regards,
    Seeya
