License type and typical usage

License type

MonolixSuite2024R1 licenses can be of the following types:

  • Individual license – named user. The named user can install and run MonolixSuite on a computer.
  • Server license – concurrent access. MonolixSuite run on an application server and a predetermined number of users can use it at the same time.
  • Floating license – concurrent access. The license is hosted by a license server, and MonolixSuite can either run on a server or individual workstations.

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 expired.

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 PKanalix, 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

  • when the user accesses to MonolixSuite with its own computer
  • when the user accesses to MonolixSuite through a remote access and wants its own dedicated license.

Server license

In that case, MonolixSuite runs on an application server. The activation key (provided by Lixoft) must be copied into the following folder of the server: monolixSuiteInstallationFolder/config/system/access
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

  • when the user accesses to MonolixSuite through a remote access. In that case, all the license management is defined by the IT.
  • when the user accesses to MonolixSuite through a shared directory (via CIFS, Network drive, NFS, …). In that case, if the IT provides Lixoft with all the MAC address of the users, Lixoft can provide a dedicated license key to the IT in order the user not to have to provide a license key when running.

Floating license

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

  • when the user accesses to MonolixSuite with its own computer and just need a license that points toward the license server. In that case, the IT provides the user a license key (using the license server management system),
  • when the user accesses through a remote access or a shared directory. Then, the license key is provided by the IT (using the license server management system).

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