For anybody else thinking of using this add-on, I can confirm that it works perfectly, and the installation is much the same as for any other add-on that has an admin component and simpler than some.

It's sad to see the developer, who has donated this really useful add-on for free, and written documentation in a language very different to his own, being unfairly criticised because a small number of users (out of 40k+ downloads) have problems installing it.
