Chrome uses an entirely different and separate Flash Player plug-in than IE does. THAT'S one reason it works when IE won't.
The other can be summed up in three words "User Agent Strings".
Without getting really techincal... User Agent Strings are what a website uses to "identify" a browser, and provide the proper content for it. That is based on the "browser engine" which matches the Strings written into the browser code.
IE uses a "Trident" engine with ActiveX controls.
Firefox uses a "Gecko" engine - no ActiveX.
Chrome uses a "webkit" engine - again, no ActiveX, but a different plug-in, called PepperFlash.
Microsoft thought they were being smart when they wrote IE11's code and the changed the User Agent Strings so it identifies as either "Gecko" or Webkit". The problem with this is: Once the ID is made and the content is directed, it REQUIRES the proper browser engine. When IE doesn't have a matching engine for the content, the web page(s) fall back on "unidentified" as the browser type.
If a browser is "unidentified", so are the plug-ins, including Flash Player... even if it's enabled and fully up to date.
Since Chrome is properly ID'd, it works. Same with Firefox, Opera or Safari if you use them.
IE is the only one having this problem and Microsoft isn't about to do anything about it, because it was intentional on their part.
If you like Chrome, I'd recommend using it instead of IE.
You may also want to look at the other browsers I mentioned.
I have and use all five (IE, Firefox, Chrome, Safari, Opera) because, as a web designer I need to test pahges in all five. Personally, I prefer Firefox, but anything will work better than IE11 will.
