In the following page, you have information on installing Flash Player on PowerPC-based Mac machine. http://helpx.adobe.com/flash-player/kb/installation-problems-flash-player-mac.html#main-pa rs_header_1
Did you try those steps?
Hi Sunil,The info on this page implies that my mac isn't up to spec to run Flash player version 11. Is there an earlier version of flash player that will work on my machine?ThanksNick

'flashplayer10_1r102_64_mac_sa.app.zip' is not the correct install file (this is a 'standalone' version of Flash Player). To install Flash Player, use the file named 'flashplayer10_1r102_64_ub_mac.dmg'.
