I need to move my current Dude software (on a Win 7 CPU/ version 3.6) to another Windows CPU. Where would I download the last version of The Dude that would run 'standalone' on windows CPU?

I'm running DUDE Version 3.6 on a singe Windows 7 machine for years to monitor a Windows environment. I see no software package for the newer releases of The Dude to run 'stand alone' on a typical Windows machine.
Did I miss something???
