I'm getting an error message when installing Flash on my Macbook running the most current version of Mavericks. It starts to install, then says "Could not complete installation" and the only option that I have to quit the installation. I have closed all other applications, so I'm at a loss as to what is causing this problem. Please assist.
Download the FULL offline installer here: Flash Player 188.8.131.52 (Mac OS X)
Save it (Download Linked File as) and Quit Safari.
Double click the saved file and "mount the DMG" on your desktop.
A window will open with the installer - DO NOT RUN the installer from here!
Right click it or Ctrl+click it and "Show Package Contents"
In Contents/Resources, double click the Adobe Flash Player.pkg
A "COCOA" Installer will open.
Folow the instructions to install Flash Player from there.
Then eject the DMG and you're all done.
