Charts v2.7.0 used a Flash express install technique that worked in Flash Player 6.0.65 and up. In 2.8.0, Charts uses the new SWF component that has a different express install technique which only
works in v8 and up. Corporate Windows XP SP3 workstations are still liable to have Flash 6.0.88, and this is also the Flash version in the IE VHD images published by Microsoft.

This is a regression for the Charts component, but the code is now in the SWF component, so I'm not sure how to assign the ticket.

Fortunately, the patch seems to be quite simple. If you think this is a nontrivial patch, I would be happy to sign a release, submit it via github, or whatever:
