Older Rhino 8 versions. Where are they?

Latest version crashes; need to downgrade.
I checked everything in “my account” and the download
section, but I cannot find any links to previsous verseion.

My latest backup is only hours ago, but I really would
appreciate just installing the old, working version.

Where can I find them?


EDIT: Windoze version

I sent a reply in a direct message
