I'm trying to install Flash Player 17 on a Mac running Yosemite, Safari 8.0.4. I've uninstalled the previous version. The installer download freezes at 25% of the download.
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
