It is recommended to install the latest DSLS (DS License Server) release.

The minimum requirement for using a current Dassault Systèmes product is a DSLS Server Release that matches the year of the respective product release, e.g., CATIA V5-6R2022 requires at least DSLS License Server Release 2022x. Older CATIA releases with DSLS licensing will still be functional.
