So, it looks like Adobe has changed the Flash Player install AGAIN. Different file name, different path to binary. And now running the installer from the command line no longer works. PLEASE, no "Well, just double-click the installer" replies... if you only have to worry about one or two Macs and don't mind walking around, that's fine, but that isn't an option in my environment.
Error I'm getting:
Mar 26 12:38:41 imac Install Adobe Flash Player[46160] <Error>: kCGErrorFailure: Set a breakpoint @ CGErrorBreakpoint() to catch errors as they are logged.
_RegisterApplication(), FAILED TO establish the default connection to the WindowServer, _CGSDefaultConnection() is NULL.
~/Library/Logs/FlashPlayerInstallManager.log does not contain anything useful, just old entries on some machines and nothing on others.
Looks to me like someone was just a little too GUI-happy when they packaged this version. I can't think of any reason to be calling "WindowServer" from the shell.
