DSLS installation guide for Windows

This is the 2026 version of the DSLS installation guide. if you have any questions, please reach out to our support team at support@vias3d.com and one of our support engineers will get back to you.

DSLS media is available on the DS media site https://software.3ds.com. This site requires you to login with your DS Passport. If you don't already have one, you can create one here. Once logged in, all licensed software will be available to you. What you see may look different to that shown in the following slides, but they should still provide guidance to get to the media.

Note that the license server does not need to be a powerful machine. It just needs to be on all the time to provide the license service to client machines for floating license configurations.

*For single seat configuration, the machine will host the license server and the full installation of CST Studio Suite.

*DSLS license server can be installed on a physical machine or virtual machines running Windows server 2019, 2022(at the time of writing) on which the Hyper-V role has to be added and a TPM 2.0 activated. For more information, please refer to the official DSLS Installation and Configuration Guide.
