How to setup SIMULIA Established Product License using Managed DSLS

What is Managed DSLS?

Managed DSLS is also known as Managed Licensing service.

The managed licensing service provides you with the ability to run certain levels of on-premises DSLS-enabled apps. Which means that DS now offers the possibility of a managed DSLS which serves as an alternative to a locally installed license server.

With Managed DSLS, you have the advantage that no physical machine is required to install the DS License Server. The license server is fully managed by Dassault Systèmes and located in Dassault Systemes Cloud Datacenter.

You can also set the environment variable DSLS_AUTH_PATHNAME using a full pathname (UNC supported), if you decide to store the file in a different directory from the default one.

For Example: DSLS_AUTH_PATHNAME=G:\Shared\MyAuth.LIC

NOTE: If you do not set the DSLS_AUTH_PATHNAME variable, and there are several authentication files in the default location, only the most recent file (which supersedes the others) is taken into account.

  1. Retrieve the service connection host name’s from the e-mail you received and declare them in the DSLicSrv.txt file located in the above default directory given in step 2#. The port number should be 443 as follows:,,

  1. Check your network configuration (firewalls and proxies) to allow https access to the three hostnames on port 443.
