LeanFT installation guide

This section includes instructions for installing LeanFT on the various supported environments, as well as post-installation and uninstall procedures.

This guide covers LeanFT versions 14.50 through 14.53. Any specific changes are indicated where relevant.


System requirements

Ensure that your computer meets all system requirements listed in the LeanFT Product Availability Matrix.

Required permissions

Ensure that you have the required permissions on the computer.

Before installing LeanFT

Install a supported version of Node.js (8.9.4 or later)

To download and install Node.js, see the Node.js website.

If Node.js is not installed, you will be prompted to stop the installation, install Node.js, and then start the installation again.

To verify that Node.js is installed on the LeanFT machine, run the following command with the same user used for the installation:

node -–version

This command returns the Node.js version installed on the machine.

(Windows only) If the command fails to return a version number, make sure that node.exe is defined in the PATH environment variable.

If Node.js is not found during a silent installation, the silent installation will fail.

(Linux only) Make sure that the libgconf-2-4 package is installed.

This package is not required for the LeanFT installation to succeed, but must be installed to run the LeanFT engine, Object Identification Center, and Test Recorder.


If you intend to use LeanFT from within your IDEs (LeanFT plugin), make sure your IDEs are already installed.

The LeanFT plugin is currently available for Visual Studio (Windows only), Eclipse, Spring Tool Suite, JBoss Developer Studio, IntelliJ IDEA, and Android Studio.

Note for Eclipse Kepler/Luna users:

To use the Eclipse IDE for Java EE Developers or Eclipse Standard editions with the LeanFT plugin, you must deploy the Google Gson plugin to your Eclipse folder:

  1. Download the Google Gson plugin, version 2.1 or later, from MVN Repository.

  2. Copy the downloaded .jar file to your <Eclipse deployment>\plugins folder and reopen Eclipse.

For more details, see the LeanFT Product Availability Matrix.
