I was having trouble installing the latest version of the flash player on my mac, so I uninstalled and tried to install the flash player again. After downloading, I open the installer, enter my computer password, etc., and then after about 20 seconds of sitting idle, the installer simply quits and disappears from the dock.
This still stays on the desktop though:
Nothing comes up saying that anything "quit unexpectedly".
I've been browsing and trying the solutions to other problems posted in forums, but nothing works at all.
I have OS X 10.7.5 and my default browser is safari.
