I am on a Mac running the last version of Snow Leopard before Mavericks, 10.8.5. I am unable to install the new Flash Player 12.0.0.4--at about the 50% mark on the installing bar, it stops and I get an error message that installation failed. The version I had previously for some time, either 10. or 11. worked perfectly but I am not unable to reinstall any previous version either. So I have a project I cannot run that requires Flash Player and can't watch videos.
I found someone in a forum who mentioned he'd seen several people on Snow Leopard unable to install Flash Player but his directions to overcome that which did work for someone who tried it, appear to be for PC's: from his first direction of right-clicking, I didn't get the option he says to click on that starts the process.
Can anyone tell me how to install this new Flash Player in a Mac on Snow Leopard? Should I trash all the new versions of the installer and the Flash Player Debugger Version 11.4.402.287 (11.4) that I have from a previous installment, prior to trying again?
Thanks for any help.
