That seems to be the latest beta but not for the 64bit since only 32bit links are present for IE and other browsers as well as for Linux and Mac. There's nothing on that specifying the 64bit.
When running a search for 64bit flash players the only notation comes up.

I saw the notice on the preview. I think most of us are still waiting to see a working 64bit player to run the 64bit IE. That will still be some time to see however.

The "Square" Preview mentioned by Airbot, kellymac35 and LittleMutt works fine for me on 64 bit IE9 (random YouTube clip shown below for demonstration purposes only):
If you run a search for the 64bit flash player that page regarding the attempt to install the 32bit flash player while using a 64bit browser will be seen as one of the results. You can look all that over at Flash Player on 64-bit operating systems
