Flash Player 11.8 install fails with error code 30 listed in console I am installing the most recent Flash Player 11 for Firefox/Safari, and after running the .pkg from Finder the installation always fails at 50%. I find this error in the console at the end of installation:

12:46:07.910 Adobe Flash Player Install Manager[1628:707] 
Install failed with error code: 30.


This has happened for the past few minor releases, not just current (11.8.800.94). How can I complete the installation? I am running Mac OS X 10.7 Lion.
I completed the installation by running the installer as root from the shell, under its mountpoint at /Volumes. The full path to the installer executable's directory is /Volumes/Adobe Flash Player Installer/Install Adobe Flash Player.app/Contents/MacOS

This thread in Adobe forums describes the underlying problem - the current user can't write to a directory the installer needs. Instead of chmod'ing the folder, I already had root enabled, and went from there successfully.

Update: Commentor is right, root is too risky. Follow the chmod route.
