^^^ When you run it, you have to click on the "Internet" button - that takes you to a web-page which triggers an User ID / Unlock key e-mail; when that eventually arrives, you enter those numbers in the fields on that first splash screen, then the software unpacks and installs, and asks you again for the unlock key. It is cumbersome, I agree, but it works.
The user interface for the software feels quite clunky and unrefined compared to Silver Efex Pro, but it seems to be quite powerful - and it processes RAW files directly, not just TIFF and JPEG. Quite cool
