Based on comments on their website other users have encountered the same problem (https://visioncolor.zendesk.com/hc/en-us/community/posts/115000159505-Can-t-install-ImpulZ). It is difficult to understand why it should take three weeks to email out a link to a properly functioning working installer for ImpulZ. Btw, my follow-up email from 21 March was ignored.

So be mindful that when you buy software from VisionColor. If you are bit unlucky -- just like me and many other users who upgraded to macOS Sierra -- you may not be able to use your product very long.
