if you search Adobe's website for the words Flash Uninstaller, you should be able to find that page, and they have uninstallers for various OSes.Friday, April 13 2007 @ 06:12 AM PDT

Couldn't find an uninstaller as part of the downloaded Flash Player package. Are you using a third-party uninstaller program?Thanks for the recommendation!
