Being able to access multiple versions of V5 through the Design with CATIA V5 widget

@YB 

You mentioned for me to message you on a questions I asked in the recent webinar.

You said there was a tool that can be used to allow 3DExperience to identify multiple versions of V5 on my machine so I can select them open choosing the Design with CATIA V5 widget.

How can I gain access to this tool?

Thanks,
