I have tried numerous times to install Adobe Flash Player (versions 10.3.183.5 & 18.104.22.168) on Mac OS X Lion. Every time the installer proceeds to approximately 5% completion, then fails with the following message:
The installation failed. Get support.
From searching other threads I found the recommendation to run the uninstaller package, then download and re-run the latest installer package. The uninstaller package runs fine, but the installer fails again. Another thread recommends to control-click the Install Adobe Flash Player Application, then Show Package Contents, then open the Contents/Resources folder to find the Adobe Flash Player package. When I try to run this package I receive the follwoing error message:
The Installer is damaged. The Installer can't open the package. There may be a problem with file ownership or permissions.
I have tried downloading the installer different times from both the Adobe website and download.cnet.com with no success. This is a factory install of Lion and I have installed several other applications on this Mac with no problems. I have installed JRE and ensured that that the Flash Player plugins are not currently installed in my Internet Plugins folder of my Library and the core Library. I have installed Google Chrome and flash runs fine with it's flash player plugin.
Thanks in advance for any advice.
I cleared my cache by using the Safari/Reset Safari menu item (which deletes a lot of stuff), cleaned out my downloads folder, then emptied the trash. I used the direct link to the Mac installer listed in the linked article. Same result for both methods of opening the installed package. I checked the file information for the installer downloaded and it showed the most recent download time for the version 11 installer.
Also, just for grins, I downloaded the installer using Chrome. No luck that route either.
are you using the uninstaller that is also linked in the FAQ?
