@Reinhard,
I don’t know with any certainty, but based on past experience with promos and giveaways like this I would not risk it.

A further update to my last post: I’ve since found settings in this program that seem to govern its behavior — when and where it steps in to do its thing. With rare exceptions, I much prefer a program NOT to constantly pop up and offer to intervene with something. Ideally, it should appear only when summoned by the user, to perform a specific task. And it should not clash with other installed programs. (This is one advantage you typically get from portable programs.)
