How do I go back to the old Acrobat?

Adobe seems to think they are not replaceable. It's a simple matter to uninstall Acobat Viewer and use Chrome (or other PDF viewers) instead.
For some reason they decided they had to fix something that was not broken and, in that process, deliver confusion and a bad UI instead of making things better for users.
Anyhow, glad someone was smart enough to allow for disabling of the new UI. I got very close to just deleting Acrobat from my system. I am busy enough to add further aggravation to my day.
