Flash in IE 9 but not in IE 11

Hello Forum,

I am using a small flash object in the index page of www.gelsana.com. It appears on one computer using IE 9 but not on another computer using IE 11. I first thought it might be an issue with a virus, but I ran a couple of anti-virus programs and I still have the issue on the computer using IE 11. Any advice?

What I would prefer to do instead of just not showing the little flash object is post some sort of message instead telling the user to download this or that. But since the cause of it not showing, I guess, might be for several reasons, I would need some sort of browser sniffer. I mean, it does not show at all in Chrome or Firefox.

Can the problem be fixed with using a later version of flash?
