Where to find Basic Viewpoint add on verion 1.3.1?

Hello,
I need to use Capella v 1.3.1 and in order to open some older models I need to install all the viewpoints in the correct version (i.e. 1.3.1). Thats fine for the majority of the add ons, but the “add on summary” page unforunately does not provide any link to the older versions of the basic viewpoint add on. Does somebody, where to find it?
Thank you very much in advance. Regards
Markus
