License type and use

License type

MonolixSuite2016R1 licenses can be of the following types:

In any case, a license key number or file is generated. Notice that the license request is only done when no license is available on the user’s computer or when the license expires.
Two folders are key {MonolixSuite2016R1}/config/system/access and {MonolixSuite2016R1}/bin/Monolix_mcr/runtime/config/system/access, where  {MonolixSuite2016R1} corresponds to the directory where MonolixSuite 2016R1 is installed. In the following, these folders will be refereed as KeyFolder1 and KeyFolder2 respectively.

Individual license

The activation key (provided by Lixoft) must be entered in the dialog box titled “Lixoft license activation” (“With activation key” tab).


In that case, the license is copied into {UserName}/lixoft/license. The dialog box only appears when no license is available on the user’s computer or when the license expires. Our software is available with independent licenses for Mlxplore, Monolix and Simulx if you just need a particular product. We also propose a license for the Monolix Suite for you to take full advantage of the integrated visualisation, modelling and simulation features.

When do I need an individual license ?

Two main cases

Server license

In that case, MonolixSuite runs on an application server. The activation key (provided by Lixoft) must be copied into the following folders of the server: KeyFolder1and KeyFolder2.
With that, each time a user starts an application of MonolixSuite, it takes a token from the license for the application under consideration. If all tokens are used (too many users use the software), a popup titled “Lixoft activate” appears and the user is supposed to add its own license or buy other licenses to increase the number of tokens for the server license.

When do I need a server license ?

Two main cases

Floating license

The use of a floating license requires to set up a license server. Two utilisations are possible:

The setup and configuration of the license server is described here.

Roaming license

RLM has the ability to allow a floating license to roam to a system which will subsequently be disconnected from the network for a short period of time. The resulting license can be used for the number of days specified when the license was set to roam, and is checked back in automatically at the end of this. In addition the user can return the roamed license back to license pool early if this is desired. See License activate tools (which can be launched from the Monolix interface, in tools menu)


This feature is enabled on demand. An extra activation key will be provided by Lixoft and the procedure to get the roaming license feature is identical to the installation of a floating license. To enable this feature, the file system.xmlx (stored in both KeyFolder1 and KeyFolder2 directories) must be modified by setting to “on” the roaming option:

<?xml version="1.0" encoding="utf-8"?>
<userPath windows="%USERPROFILE%" linux="$HOME"/>
<license activation="" roaming="on"/>
