Why are my users getting a message about needing Flash Player 10? Dec 22, 2010 By Sunny Bozell We have a client that keeps getting a message that they need to upgrade to Flash player 10 when they play the course. The course consists of flash slides that were developed with Flash player 9, and a couple with version 6 and 8. Should they be getting this message? Should they have to upgarde with Studio 09 products? Thanks!
