I have just recently updated to Flash Player 14.0 and I'm using FF 30.0. I always save the file to my downloads folder before running it. I encountered two errors (same one twice) while installing the update. I'm a Web and Software Developer. I have Visual Studio installed and the Just-In-Time Debugger caught them, displaying the following error message:
"An unhandled exception ('Script Breakpoint') occurred in install_flashplayer14x32au_mssd_aaa_aih.exe [1924].
The Just-In-Time debugger was launched without necessary security permissions. To debug this process, the Just-In-Time debugger must be run as an Administrator. Would you like to debug this process?"
After declining to debug the process twice, the installer completed successfully and so far, Flash Player 14.0 has been working fine. If you are still unable to install version 14.0, I suggest just using the previous version until Adobe gets this fixed. You can download previous versions from here: http://helpx.adobe.com/flash-player/kb/archived-flash-player-versions.html.
