I might suggest a difference approach, because there has been a shift
recently... it's now usually more valuable to detect the level of the
visitor's SWF capabilities, rather than just whether they have a Macromedia
Flash Player.

The MediaMetrix quarterly consumer audits show that over 95% of consumers
can immediately view SWF content in their current browsers, without
downloading anything new. However, if you're relying on the predictable
interactivity engine within the Macromedia Flash Player 5, then by March
this instant viewership was only 55%. I'd guess we're now in the 65-70%
viewership range here in May, considering there are three-million-plus
completed downloads each day... regardless, very few don't have *any* Flash
Player, but some have older ones.

Here's the March audit:

ation.html>

(Methodology info, sample tests and more are up a directory level.)

Your SWF file itself can check which version of Player is rendering it, via
the "getVersion()" function. In IE/Win it's easy to specify a minimum
version via the CODEBASE attribute of the OBJECT tag. There's also the
Macromedia Flash Deployment Kit and other approaches too.

Generally, it's more valuable to have the SWF file test the version of its
rendering Player these days... almost everyone has at least some Flash
capability, but it's useful to check whether this capability matches your
particular content.
