Viewpoint detachment

How can I detach a viewpoint from a project?
Indeed Capella has linked one of my Projects to a viewpoint that was installed on my computer, even if I didn’t used this viewpoint in my project.
In order to share this project with other people I need to detach the viewpoint.
I didn’t find any entry in the Capella help section.

So I found out that another post was dealing with this question:
(I may have been too quick when asking the question, sorry).
However, the link from the download section of Capella website does not work anymore, and when I try to install the patch attached to the previous post, I have the following message in Capella: no software site found!
Any clue?
