Yeah, I don't think their system is geared for that... My download link was dead when I tried it again. I've upgraded my CAD Computer to Windows 10 and luckily I still have the Setup file. It might be worth searching the computer for the Setup file and backing it up. Mine's on a USB ready to go again; I just hope the licence code works again.
From Vectric's website, go to Support > Customer Portal, and you can log in and get license codes and download your software.
