I acquired an academic license but for some reason I try adding the analyst module that I downloaded from the modelio website and it "loads" but it never appears in the list of modules so I can activate it in my current project.
First, you have to activate the Analyst workbench. This video www.youtube.com/watch?v=9mqNrU0GP5c&t=334s
should help you to understand how to activate a specific workbench.
Then, you go to the workmodel and you have to create a subproject Analyst.
Please note that Analyst is not a module anymore. You have downloaded a module compatible with Modelio 2 so you cannot use this module. Analyst is now a feature available on Commercial version of Modelio.
