»» NOTE: Starting with Simio 16.255, RLM v15.1+ is required. This is only for users of on-premises licenses managed by Reprise License Manager (“RLM”). Users of on-premises network licenses provided/managed by QLM are not affected. See 16.255 Release Notes for more information.

»» NOTE: Simio is designed to be backward compatible, meaning you can open projects/models created or saved in older versions of Simio using newer versions. It is not recommended to use an older version of Simio to open or make changes to a project/model if that project/model was created or last saved in a newer version. If you want to share projects/models with others, make sure they are using the same or a newer version of Simio. Maintain a copy of your project/model in the Simio version where it was originally created or last saved, and then create a separate copy for use in a newer version of Simio.
