The End Of Life (EOL) for Adobe Flash Player is December 31st 2020.
All remaining Flash Player installations on university computers will be removed by December 31. No further installations will be permitted, as per Adobe, and for the security of the campus.
If you have content that requires Flash Player to display, you must figure out an alternative method. See Adobe’s article at https://www.adobe.com/products/flashplayer/end-of-life.html for details.
