At https://www.rdctools.com/downloads/ you can download DUF 2.1.1 or, at least, this is what is shown at the installer. However, If I go to https://www.rdctools.com/HTMLHelp/Wh...sion20200.html I see that it is on version 2020.0.0.0 right now, even more, version 2.1.1 doesn't exist.

Can anyone point me in the right direction?

BONUS: I need the latest version compatible with DF 19.1
