Workaround found: Install Adobe Flash Player.app seems to be damaged

[UlfDunkel]

Like many other Mac users, today I tried to update to the latest version of the Adobe Flash Player. The downloaded Install Adobe Flash Player.app (v3.3.9.0) seems to be damaged. It seems to have been inappropriately altered so its code-signing no longer works with the Mac OS X Gatekeeper. Even worse, switching the Gatekeeper off won't give any better chance to run the Installer.

This is what the Console tells:

05.02.14 14:29:08,565 coreservicesd[65]: Application App:"Install Adobe Flash Player" [ 0x0/0x7b07b]  @ 0x0x7f93206ca360 tried to be brought forward, but isn't in fPermittedFrontASNs ( ( ASN:0x0-0x7d07d:) ), so denying.

Google pointed me beside others to this page which informs that users won't have a real chance to fix it:

It seems as if this isn't new to Adobe:

Counting this and the big bunch of error reports in this forum, I guess you Flash developer guys here at Adobe should check and fix the Installer soon.

Thank you in advance.

Edit:

Here is a workaround that worked for me: Download the Flash Player archive 12.0.0.44 from this Archive page:

http://helpx.adobe.com/flash-player/kb/archived-flash-player-versions.html#Flash%20Player%20archives

When it is unzipped, you will find a folder named fp_12.0.0.44_archive in your Downloads folder. Open its subfolder 12_0_r0_44, and run the flashplayer_12_0r0_44_mac.dmg.

Flash Player 12 (Mac OS X)

That's the same file (flashplayer_12_0r0_44_mac.dmg.) in the zip.

[UlfDunkel]

I hope so, but I didn't blame the flashplayer_12_0r0_44_mac.dmg, but the Adobe Flash Player Installer.app which cannot be launched successfully on Mac, so it won't download and install the flashplayer_12_0r0_44_mac.dmg.

You're right. That's one reason I ALWAYS update manually.

Hi UlfDunkel,

The file you are referring to,

Install Adobe Flash Player.app(v3.3.9.0), is a 'stub' installer that, when executed, downloads the actual Flash Player installer and installs Flash Player silently.  I've executed this 'stub' installer on OS X 10.8.5 and it installs Flash Player successfully.  What version of OS X are you using?  And, if you still have it, what is the file name of the installer file that you downloaded?

Thank you in advance.

Maria:

You exactly describe what Adobe expected the stub installer to do. But on my 10.8.5 system (as well as on many, many other users' Mac systems, as you can see from the big amount of complaints in this Forum), it didn't work, as described in my Console log above.

The downloaded installer archive is named AdobeFlashPlayerInstaller_12_ltrosxd_aaa_aih.dmg, with a size of 961 KB (961,150 Bytes, 2014-01-11 07:20).

The only way how I could manage to run the update successfully, was to download the Flash Player archive 12.0.0.44 from the Archive page mentioned above.

I have upgraded to Yosemite but had this problem prior to that.  What I did find that work was to use the Disk Utility.app to recreate the dmg file.

Try this:

Right click on the dmg in Finder.

Choose: Open With->Disk Utility.app

Once open:

Select the dmg image at the bottom left in the list view.

Choose First Aid tab

Choose Verify

Choose Repair

On the Top Toolbar choose Convert

Use standard selections and place the new image on the Desktop

Dbl click on new DMG image file and it should work.
