Is there an alternative for adobe flash player? I can't continue my course with it. Please let me know if there is.
There is no alternative to Flash Player. It's unfortunate your school didn't migrate course content to some other technology prior to Flash Player's end-of-life.
Adobe announced Flash Player's end-of-life in July 2017, three and a half years ago, giving content creators, programmers, developers and IT experts over 3 years to migrate their Flash content to a different technology.
Major browser vendors are deprecating Flash Player support. For details specific to each vendor, please refer to:
For users attempting to view Flash content, contact the content creators and inquire about their plans to migrate their content to some other technology.
For enterprises dependent on Flash Player, please refer to the Enterprise end-of-life FAQ:
Enterprise Enablement may be an option until such time all browser’s remove support for Flash. Technical details can be found in the Flash Player Admin Guide, pages 28-35):
