The Studio 5000 Multi Version feature is a game-changer in the realm of control system design. It allows users to open and work on projects created in different versions of Studio 5000. This compatibility is a significant advantage, especially in projects where collaboration among different teams or partners is required, and they might be using various versions of the software.

: Keep a "Legacy VM" for versions 10–20 and a "Modern VM" for versions 21–36.

Double-clicking an .ACD file always opens the last installed version of Studio 5000, not the version it was written in.
