DSLS (Dassault Systèmes License Server) is a licensing system developed by Dassault Systèmes that provides such benefits as:

• License usage statistics, debugging, and simple UI to administer and view statistics.
• Licenses are bound to expiration date rather than product version.
• Nodelock, floating, and managed licensing options.

DSLS and modeling tools compatibility

* To run DSLS 2024x licensing on Linux, glibc 3.4.20 (at a minimum) is required.

**IMPORTANT. To use modeling tools with DSLS licenses, Microsoft Visual C++ Redistributable must be installed (see Latest supported Visual C++ Redistributable downloads). This applies to Windows OS only.

DSLS hosting restrictions

• DSLS servers can only be hosted on physical computers (with the exception of using HyperV virtualization; see the Installation Guide).
