I am an Educator who relies on a library of excellent Shockwave animations. When I play a shockwave animation at work(school), a box opens asking me to use Flash Player and then the animation plays. At home on my iMac and Macbook, shockwave animations have stopped playing altogether. I just can't imagine that so many educators would have to walk away from such a welth of excellent material.
My question is this: How can I continue to use these shockwave animations on my Macs? Does Flashplayer run them too?
Flash Player and Shockwave Player are 2 different technologies and require 2 different products to play back animations.
If you're being prompted to use Flash Player, then it sounds like the content you are attempting to view is Flash content, not Shockwave content. Shockwave content requires the Shockwave Player, not Flash Player, which Adobe discontinued for Mac in March 2017 (https://helpx.adobe.com/shockwave/shockwave-end-of-life-faq.html). If you have Shockwave Player at work, your work most likely has a license and is allowed to use Shockwave Player for the duration of the current contract (as per the linked FAQ)
SWF files are the ones that need Flash Player. So they will run to the end of the year, then stop.
Are you aware that Flash Player is going away at the end of the year? The producer of those animations needed to make them again. Contact them to find if they did this.
