I don't think a trial is offered.
Hiarcs Chess Explorer Trial

Seeing sales of Hiarcs and Houdini along-side Fritz all over the place now. What does this mean? Are players quietly moving to pay-per-use online services with neural network databases such as LiChess0 and Deep Fritz to enhance their opening repertoires with fresh ideas that these 128-core engines cannot produce?
I'm looking for a HIARCS Chess trial but can not find it anywhere. Can someone help me?
