https://get.adobe.com/shockwave/ is allegedly still a thing that exists and that you can install if you have Windows. It says it works on Windows 7 and 8, IE, and Firefox. My guess is that they haven't updated that, and it'll no longer work on Firefox since Quantum, but it's likely some flavor of IE will work with you there. And my guess is it'll work on Windows 10 with IE, since most things that work on 8 work fine on 10.
