Hello and welcome to the Community,

This popup informs you which versions are used in the project you’re opening (Version in Project) and versions which are installed in the currently used Automation Studio (Installed Version). By clicking the “Download Required Version(s)” button, the versions used in the project should be downloaded if available.

Mapp Motion version 5.20.1 isn’t publicly available for download due to the dual-use restriction. To get the version, contact your local B&R office.
