Failure to install - Black Window.

[vexvoir]

Every time I have tried to install the new flaw player, it will begin to have the progress bar but then will go black. I have restarted the computer, closed Safari, and downloaded this file numerous times on a stable internet connection. I have a Mac Book Air OS X 10.8.5, and it has never given me issues with updating my flash player until now.

I'm having the very same problem  Mac OS 10.7.5 and Firefox 34.
