Harry Potter and the Order of the Phoenix is designed to visually match each environment in the 2007 film. Gamers take the role of Harry Potter, Sirius Black, and Professor Dumbledore as they explore the areas in and around Hogwarts. The teachers and officials in the magic community refuse to acknowledge the return of Voldemort, and so Harry and his friends have started training other students how to defend themselves against the Dark arts. Other aspects of gameplay include attending Herbology, Charms, Transfiguration, and Potions classes as well as completing side-missions for professors.
Harry Potter and the Order of the Phoenix is abandonware and no longer sold or supported by its publishers. Files are archived here for these platforms:

How to play on Windows (Have to install)
In the case of games specifically like this, the install version may set off their anti-virus software or even (in the case of Windows Defender for Windows 10 users) completely restrict them from executing the setup, despite it being a false positive as opposed to an actual virus (since virus detectors will always scan cracked files as “trojans”). So the pre-installed version works around that potential issue.
