You need Flash Player to view some of the content in the PDF or PDF Portfolio you were viewing. PDFs can include media, such as an animation or movie, that requires Flash Player to display. Adobe Reader and Acrobat no longer include Flash Player and features that require Flash now leverage the machine’s local copy of Flash. This new strategy allows users and administrators to manage Flash Player updates independently of Acrobat product updates.
Note that the Flash Active X component is not enough to display this content. A full Flash player must be installed.
Make sure your computer meets the system requirements noted below, then download and install Flash Player using the link provided. Enterprise admins should download an installer suitable for distibution across their organization by starting here: http://www.adobe.com/products/players/flash-player-distribution.html
