Same problem as everyone else - on a mac, installer gets stuck at 25% downloading and then stuck. Tried a clean install, doesn't help. Have same problem with Adobe Reader making me guess this is a mac os / adobe issue. Any help would be greatly appreciated.
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
