OS X version: 10.9.5
Safari version: 7.1.3 (9522.214.171.124)
I have the same problem with Mavericks, only it hangs after briefly displaying the fill gauge. when I close the install window, Safari kicks in with a window saying “Adobe Flash Player could not be installed.”, and a restart button.
If Adobe provided a dmg of the plugin itself that I could download, I probably could solve the problem: it is their downloaded installer that is hanging.
I have never had this problem before until I switched to Mavericks: version 126.96.36.199 of the plugin is claimed to be out of date when trying to display Flash data from a variety of web sites. An earlier version of the plugin (188.8.131.524) will display some sites, but no recent ones.
I have disabled antivirus software and checked that Adobe is not on any prohibited lists. Unless Adobe is using really strange download protocols, the firewall in my ADSL modem router shouldn’t b causing any problems, and i hasn’t in downloading with previous operating systems. The problem is clearly an interaction with the Adobe installer and OS X 10.9.x and 10.10.x.
I'm also on Yosemite -- 10.10.2 (14C109) -- and the problem I'm seeing is that the install downloader tool hangs at 25%. It's not a network problem, as far as I can tell. I wondered if it might be having problems with the existing files, so I ran the un-installer, and that seems to have worked -- my browsers don't see the plugin anymore -- but the installer is still doing the exact same thing. (I also deleted and re-downloaded the installer, so it's not that.)
I have exactly the same problem! and I have done the same actions!
Try downloading the "offline" version from
I had a similar issue and this resolved it. Please make sure you download the correct version for your operating system
@JerryWe's solution appears to be working for me. Thanks!
I just figured this out on my own as no one at Adobe will release a playbook that gives proper instructions on this issue. If you are having issues with the application not installing all of the way, you have a permission issue on the the partition where your Yosemite OS is installed. Here is how you fix the issue that you are experiencing:
- Open Disk Utility (press Command and the Space Bar, then type disk utility)
- Locate your disk and the partition where your OS installed.
- Select First Aid (in the right pane next to Erase and Restore)
- Locate the button "Verify Disk Permissions" and click on it.
- Wait, get some coffee and relax, this will all be over soon
- When Verify Disk Permissions is complete, click on the button "Repair Disk Permissions"
- Now grab breakfast, lunch or dinner and tell someone you love that you love them.
- After your disk permissions have been repaired, close out Disk Utility
- Open the FlashPlayer installation file and run the installation again.
- Finally, whew... Enjoy your entertainment fare. You made it across the schism that Adobe loves to plague their loyal patrons with.
I hope this helps someone. Let me know if it worked or didn't; I am curious if you all will see the same success that I have realized.
Cheers & Many Regards,
Just tried it. Works for me, too.
