You need to have installed a standalone flash player. Install Macromedia Flash Player (v8 for example), and then it will work!
A very good alternative is FlashBack Player (also used in a lot of tutorials)
Thank you very much.
I followed your instruction and I download Macromedia from here
I install flashplayer10_1r53_64_winax and after that the error message vanished.
P.S: I haven't tested it yet, but I also report this
