Flash Player / Your installer is broken and has been for some time

[caburlingame]

Regarding the Flash Player Installer on Mac OSx: I've uninstalled the old version, and verified that it is uninstalled.  I've updated all software on my computer and then installed the latest version of Shockwave.  I've rebooted and shut down all other programs.  Still, the installer is stuck at 25% download.  Repeatedly.  Based on searches, this has been a problem with your installer for about a year.  It's beyond imagination that your dev team hasn't fixed this.  A fix should have been out in a day.
