Guys.. do me a favor.. download 3delight.. install it... DONE.... there's no copying into x amount of folders, there's no NEED to do that. Yes this is beta, but after being advertised and promised for the last 4-5 months, or however long its been, I stopped counting months, i DO expect to be a little more buttoned up in terms of install. Especially if this is beta, which means, that there's probably a multitude of builds coming, and not everyone has the time to go through your install notes and copy/paste into folders, etc. Again.. do this.. download 3Delight, its a single executable, and installs hydra (in their own folder, not scattered throughout houdini folders)...
Thats how its done, thats what I expect from OTOY, being as long in business as you have. OTOY, you should expect no less.
