Silently installing, uninstalling or updating Lansweeper

From version 8.0 onward, you can perform a silent install, uninstall or update of Lansweeper via Command Prompt (CMD). This can be done attended or unattended and can be very useful when setting up large environments with multiple scanning servers in an automated way. To use the silent install feature, open a Windows Command Prompt with elevated permissions. Below you can find an example.

Lansweeper silent install parameters

The following parameters can be used:

  • /silent or /verysilent: with /silent, the installation progress is still shown and the cancel button is available. With /verysilent, the progress is not shown and all warning messages are suppressed.
  • /accepteula: to accept the Lansweeper terms of use.
  • /upgrade: to update a Lansweeper installation.
  • /install: to perform a new Lansweeper installation.
  • /parts: to specify which components to install (e.g. /parts ="SCAN,DB,WEB").
  • /dbserver: SQLLocalDB or SQLServer (e.g. /dbserver="SQLServer").
  • /dbinstance: to choose the SQL Server instance to connect to (e.g. /dbinstance="localhost\sqlexpress").
  • /dbuser: to specify the database username that creates the database during installation.
  • /dbpassword: to specify the database password of the user that creates the database during installation.
  • /dbuserconfig: optional password for the lansweeperuser database user, useful when installing multiple scanning servers.
  • /allowdboverwrite: forces the installer to overwrite an existing database found during a new Lansweeper installation.
  • /webserver: IIS or IISExpress.
  • /httpport: to specify the web console's HTTP port (e.g. httpport=81).
  • /httpsport: to specify the web console's HTTPS port (e.g. httpsport=82).
  • /folder: to specify the Lansweeper installation folder.
  • /credkeyfile: to specify the encryption key file (Encryption.txt) to be used.
  • /noDCOMReset: to prevent the Lansweeper installer from making DCOM changes on the Lansweeper server.
  • /SkipNpCapDriver: to prevent the Lansweeper installer from installing the Npcap driver, used by Asset Radar.
  • /ConfigurationFile: to perform the installation by pointing to a config file that contains the necessary parameters.

All parameters and values are case-insensitive, except the values provided for /dbuserconfig and /dbpassword. If a specific parameter is not provided, a default value is assumed. For instance, if you don't specify which components to install, the assumption is made that you want to install all of them. If the installation stops unexpectedly, its log file can be found by typing %temp% in the path of Windows Explorer. The log file is a .txt and will start with "Setup Log...". The final installation log file can be also found in Program Files (x86)\Lansweeper\Install on your Lansweeper server once the installation has fully completed.

Below you can find some example commands that can be used for different installation scenarios:

Example 1

The below example will perform an Easy, silent installation of all Lansweeper components. The Lansweeper scanning service, database (SQL LocalDB) and web console will be installed on the same machine.

LansweeperSetup.exe /silent /accepteula /install

Example 2

The below example will silently install all Lansweeper components with a Lansweeper database hosted in SQL Server and a web console hosted in IIS.

LansweeperSetup.exe /silent /accepteula /dbserver=SQLServer /dbinstance="localhost\SQLEXPRESS" /webserver=IIS /httpport=81 /install /parts=scan,db,web

Example 3

The below example will install an additional scanning server, with the Lansweeper database being hosted on a remote database instance "REMOTE_SERVER\SQLEXPRESS".

LansweeperSetup.exe /verysilent /accepteula /dbserver=SQLServer /dbinstance="REMOTE_SERVER\SQLEXPRESS" /dbuserconfig="your_db_password" /install /parts=scan

Example 4

The install parameters to use can also be stored in a config file. With the below contents in InstallConfig.ini, an installation will be performed of all Lansweeper components, with the Lansweeper database being hosted in SQL Server. The Lansweeper web console will be hosted in IIS Express using HTTP port 81.


The below command can be used to point the Lansweeper installer to your config file.

LansweeperSetup.exe /silent /ConfigurationFile="C:\install_files\InstallConfig.ini"
The /silent or /verysilent parameters always need to be provided in the command itself. They cannot be included in the config file.
Here is an example of a full config file with further explanations. Make sure to unzip the file.

Example 5

To install Lansweeper using an Easy, silent installation, but without installing the Npcap driver.

LansweeperSetup.exe /silent /accepteula /install /SkipNpCapDriver

Example 6

To update Lansweeper the following command can be used.

LansweeperSetup.exe /silent /upgrade /accepteula

Example 7

To uninstall all Lansweeper components the following command can be used.

"C:\Program Files (x86)\Lansweeper\unins000.exe" /silent
