Tried that,did not work.Still get same message - The following install step failed:run postflight script for plug in.
The only plugin in the Internet Plug-Ins folder was the Flash Player.plugin.lzma
There was nothing in Preferences or the Cashes folder for Flash.
I have exactly the same problem and followed the same troubleshooting advice. It's been a few weeks since your last response, were you able to find a solution? I'm thinking there must be something in the Library>Preferences folder that's corrupting the installation process.
I posted a similar message recently. So far almost 60 views, not one reply. Evidently this has Adobe flummoxed.
May have to bite the bullet and upgrade to a later operating system which of course means hours of debugging and spending moolah to upgrade other applications. (Yikes!)
