Lansweeper LocalDB Service install failed. ErrorId: -1

This article explains how to resolve the Errorid: -1 error you may encounter when installing or updating Lansweeper.

One of the available database server options when installing Lansweeper is SQL LocalDB. When you choose to host the Lansweeper database under LocalDB, the Lansweeper installer creates a service that runs the SQL LocalDB database server. Afterwards, this service will run under a user account created by the installer, NT Service\LansweeperLocalDbService. In order for the aforementioned user account to successfully run the LocalDB service, it must be granted the necessary permission to log on as a service. Lansweeper automatically tries to give NT Service\LansweeperLocalDbService this permission.

If you're using the SQL LocalDb database provider, you may encounter the error below when updating or installing Lansweeper.

Lansweeper LocalDB Service install failed. ErrorId: -1

Step 1: try to start the Lansweeper LocalDB Service

Open services.msc and start the Lansweeper LocalDB Service. If the service started successfully, restart the Lansweeper Server service and connect to the web console. If the Lansweeper LocalDB Service failed to start, proceed to step 2.

Step 2: verify the Log on as a service security policy

When the Lansweeper LocalDB Service starts, it reconfigures local Windows security policy by adding the NT Service\LansweeperLocalDbService account to the Log on as a service policy. This policy can be found in Windows on your Lansweeper server by going to Local Computer Policy > Windows Settings > Security Settings > Local Policies > User Rights Assignment in the Local Computer Policy editor, which is accessible via MMC.
Group policy may disable or override local policy in a domain environment. If the LocalDB service was unable to log on, the error below may be thrown. Additionally, an event such as the one below is usually found in the Event Viewer of your Lansweeper server. Under Windows Logs\Application or Windows Logs\System.
You can resolve this by modifying your domain's group policy in Active Directory by adding NT Service\LansweeperLocalDbService to the Log on as a service policy for your Lansweeper server. Regardless of whether you're in a domain or not, the NT Service\LansweeperLocalDbService user must be used, other accounts are not supported.
Error 1069: The service did not start due to a logon failure.
Logon failure: the user has not been granted the requested logon type at this computer.


If you'd prefer not to make group policy changes, or would like to use an alternative for any other reason, you could opt to make use of the SQL Server database provider. This will avoid the Lansweeper LocalDB install failed error entirely. A comparison between SQL Server and SQL LocalDB from a Lansweeper perspective can be found in this article. If you're performing a new installation of Lansweeper, you can perform an Advanced Install and select the SQL Server database provider. If you're already using SQL LocalDB, you can migrate to SQL Server.
A SQL Server instance must be installed and configured prior to migrating or installing Lansweeper using the SQL Server database provider. A free Express edition is available.
