I Prefer using Adobe Animate 2021 and their latest versions because it rarely crashes. The interface is more user friendly than their previous versions. It publishes faster than older Adobe Flash and Animate products.
Instructions I’ve Used:
Download GenP: Download Link
Download and install Creative Cloud - Download Link
Exit Creative Cloud and quit the service when asked
Run GenP (RunMe.exe) and Cure Adobe Creative Cloud 2021
Open Adobe Creative Cloud and install any desired Adobe apps
Exit Creative cloud and quit the service

The current adobe animate does not include Adobe Flash Player 9 in their export list, Following this Thread should help you setup Adobe Flash Player 9 from any adobe animate versions.
