Uninstall Software is an action you can run from a Windows computer's Lansweeper webpage and that allows you to remotely uninstall software from the machine. The Uninstall Software tool does not require any Lansweeper software to be installed on the target computer you're removing applications from.

The Uninstall Software tool is free and no longer requires a license. If you are getting an error that you have an unregistered version of the tool and are limited to 60 seconds of use, download the latest version of Uninstall Software, which does not require a license.

Uninstall Software has become obsolete since the arrival of Lansweeper 5.2, which includes software deployment features. As deployment packages can uninstall software as well, the Uninstall Software tool will no longer be updated or supported.

Setting up the Uninstall Software action

To set up the Uninstall Software action, do the following:

1. Add the RemoteUninst executable to the Action Path folder listed in the web console under Configuration\Asset Pages. Your Action Path indicates where the web console tries to locate your action scripts and executables. By default, the Lansweeper installer shares the following folder on your Lansweeper server as lansweeper$ and uses that as the Action Path: Program Files (x86)\Lansweeper\Actions
   
2. Add the action below to the Configuration\Asset Pages section of the web console. {smartname} is a placeholder for the computer's FQDN or NetBIOS name.
   {actionpath}RemoteUninst.exe {smartname}
   
   
   
3. Make sure your browser is properly configured to run asset actions.

Running the Uninstall Software action

Once you've verified that your machines and Lansweeper installation are configured correctly, do the following to run the Uninstall Software tool:

1. Browse to a Windows computer's Lansweeper page.
   
2. Hit the Uninstall Software button under Advanced actions and then hit Yes if you are prompted to confirm.
   
3. The Uninstall Software window opens. There are 3 types of software packages:
   
   MSI packages: these packages follow Microsoft standards for (un)installation and can be uninstalled using the MSIexec command. Adding the /QN /NORESTART parameters to the command makes the uninstall invisible to the target machine. When you select an MSI package and hit Uninstall Selected, the uninstall command is automatically formed. You can then simply hit Uninstall to proceed.
   Custom packages: these packages do not follow Microsoft standards for (un)installation and require additional parameters in order to be uninstalled silently. You must consult the software publisher's documentation to see if any parameters are available. When you select a custom package and hit the Uninstall Selected button, you are prompted to add parameters to the uninstall command.
   Locked packages: these packages cannot be uninstalled. Some software publishers do not allow their software to be uninstalled, as doing so might break Windows functionality.
