Elekdrums - where to download? Halion 3 -> 5?

I bought the Elek Drums VST Sound Instrument Set, moved to a new machine, forgot to save the installation files. But the license is stored on the dongle. Where can I download the files?

Also - if I may piggyback the question - I may want to update my Halion 3 license. But I only see a 4 -> 5 option in the shop? This has been answered in this forum before (I find Google results on the topic), but they seem to have reinvented the forum without saving the previous content.
