I have been trying to download flash to watch an exam review and it has been stuck at 30% for hours. I tried restarting the download and it went to 30% and stopped again. I am using a Mac with the most up to date software available for it.
This morning we resolved a problem that prevented Flash Player installations from completing for some of our Macintosh users.
If you encountered this problem, please delete any previously downloaded Flash Player installer and either:
1.) Download the installer again from https://get.adobe.com/flashplayer
2.) Download the stand-alone installer from http://fpdownload.macromedia.com/pub/flashplayer/latest/help/install_flash_player_osx.dmg
