Flash Player Detection Code

I have a client who would like me to change the code in a published course to detect if the user has Flash Player 11 or higher instead of Flash Player 10.  We have run into an issue with an error occurring for some users and it seems that once these users upgrade to FP 11, the error goes away.

The client wants a flash player detection code added that detects if the user has FP 11, and if they don't it displays a message that they have to upgrade their flash player before going through the course.

Can anyone help me with this?  Can I modify the existing code to detect 11 instead of 10?
