The AIDA page you are pointing at mentions “Capella model : contains the Capella models. Required environment : Capella 5.2 with the following add-ons : PVMT + Diagram Styler”
If you want to open it with Capella 6.0, you need to install first the PVMT add-on, then migrate your model
Some viewpoints are missing
The viewpoint ‘org.polarsys.capella.vp.requirements’ is missing
The viewpoint ‘org.polarsys.capella.vp.mass’ is missing
The viewpoint ‘org.polarsys.kitalpha.vp.requirements’ is missing
Well, I suppose that from the error you get, you’re missing the Requirement Viewpoint and the Basic Mass viewpoint. So you would need to install them as well.
