There is nothing to download.
Perrette is not released. This page exists so that the answer to where do I get it is a page rather than a missing link, and so that when there is something here, it is already where you would look for it.
When there is one
What the download will be.
An application that reads an authored building model, translates its geometry into something a solver will accept, and runs the analyses described under Tools on it — fire and smoke, ventilation, structure, acoustics, embodied carbon, energy, optimisation, egress.
It does not replace the solvers. It drives established engines and reports the version of each one alongside every result, because a result is only reproducible against a named version. And it stops where it should: geometry with more than one plausible reading comes back named and located rather than quietly repaired.
Platforms, installation, system requirements and licensing are not settled, and no release date has been set. Putting any of it here before it is decided would be a guess, and guesses on a page like this have a way of turning into commitments.
