Circle2 old installers?

Hi, can I get a link to old installers of Circle2? Maybe like Circle2 2.0 specifically? I have some old projects that used an old version (March 2017 I bought it) and the presets that I used are no longer available in the newer versions for some reason and the plugin is no longer even recognized when opening those old projects so there’s zero recall.
Any help would be appreciated, thanks.
