I have tried to use the UML 2.0 Design Project in Delphi XE6 Version 20.0.16277.1276, which includes Update 1 & Help Update 1. When I try to open the UML-2.0.tgproj project in C:\Users\Public\Documents\Embarcadero\Studio\14.0\Samples\UML the IDE says "No platforms exist". The modelling on existing Delphi projects works (e.g. I can paint class diagrams for existing projects). But the source code independent modelling does not work.
In Delphi XE2 I can still open its sample UML-2.0.tgproj, but not in Delphi XE6.
I checked the installer if there is any option I may have unchecked accidentally, but that is not the case.
I am looking forward to your suggestions on how to overcome this problem.
