I Give Up. How Do I Download Duncan Amps PSUD2?

I am trying to download a copy of Duncan Amps PSUD2. Is it real? Is it available?

I go to this page
https://www.duncanamps.com/psud2/

PSUD2 - last updated 22/11/2019

In the page banner, I see "Download Software" That download link takes me to
https://www.duncanamps.com/psud2/download.html

There I see:

PSUD2 has moved! You can now get the latest downloads and support from the Groups.IO page at https://groups.io/g/duncanampspsud
This page will stay live for the foreseeable future to host older versions

The new downloads page is a PSU Designer Group Forum
https://groups.io/g/duncanampspsud

And that looks like a software download dead end. So....... What is the story?
 
Did you join? Very little is accessible if you are not subscribed to the forum. I imagine the images are available on the forum. I generally use spice for these sorts of things but used PSUD2 until the early teens.

Much older versions are available for download on the legacy page, but I have no idea whether the WinNT version will run under newer versions of windows.
