Question

Flash Player update installer appearing on desktop, but fails to install - recreated on multiple iMacs

"Out of the blue" a Flash Player Installer icon appeared on all our 35 Computer Lab iMacs.

Same thing has happened on my personal iMac at home. (eliminating the possibility of it being a local network issue, perhaps)

I assume this appeared because there is a system preference setting for Flash Player allowing for Adobe to install updates (recommended).

After starting the install, we get an error message "You can’t open the application “Install Adobe Flash Player” because it may be damaged or incomplete."

This error message appears regardless of OS X version (running on 10.11.1 and 10.11.3)

I verified to make sure we indeed have the latest version of Adobe Flash, and we do.

We can remove the installer from the desktop, but it reappears a couple of weeks later with the exact same problem.

Is there a solution to this?

I have a Mac Pro running 10.6.8 and the install would go 95% and stop there

.

SOLUTION: run the uninstaller, repair permissions (don't know if this is necessary but I did it). Download the latest flash player installer but don't launch it as there is a problem w/ that installer which we will bypass.

Open the install image, rt click on the installer > view package contents > Contents > Resources > Adobe flash player .pkg (or whatever it's called). Run that only and you'll have success. It seems there is an issue w/ the install manager which we have bypassed.

Best of Luck.

Hi,

I'm only aware of one similar complaint, and we weren't able to identify the root-cause.  Our installer folks are looking into it to see if we can figure out what might be going on, but no obvious theories come to mind.

Can you think of any possible clues?  Is there a common denominator between your home and lab systems that would be distinct from your average end-user's mac?  You're using the same security suite, some non-standard OS hardening, restricted account permissions, etc? 

Anything that would help us figure out how to reproduce it in our lab would be really useful.

Thanks!

I've had the same issue on my MB Pro for a month or more. It fails mid-installation every time. I tried to do a clean install by uninstalling Flash, but the installation still fails. I've been periodically making attempts to download the installer package and re-install, but same result every time.

I'm running OSX 10.9.5. I had the same issue on my iMac running 10.11, but eventually it installed successfully.

Please see the installation troubleshooting guide:

https://helpx.adobe.com/flash-player/kb/installation-problems-flash-player-mac.html

There are links to the alternate installers at the bottom of the page.  They should get you going.

Collecting and posting the installation logs should tell me what's failing and allow me to pass that feedback to our distribution team.
