Have you tried installing from our stand alone installers? You can find them here:

Where can I find direct downloads of Flash Player 11 for Windows or Macintosh?

Are you saving the installer file to your hard drive and then running the installer from your hard drive?

I suspect we're having a problem with the code signing mechanism in Windows, though I'm surprised that saving and running the stand alone installer didn't help. Could you run the "Fix It" utility that Microsoft provides in the Resolution section of this KB article to see if that helps?

Thanks,

I can't get that far Carl as the attached error is received when I try the 'save' option.

Hi Chris,

Have run the Fix It utility and everything checks out ok.

Any other suggestions from here?

How do I do a clean install of Flash Player?

Download the files, don't try an online uninstall or install.

Could you guys check the following out for me?

1. Go to the start menu and type the following: gpedit.msc

2. In the Local Group Policy Editor dialog that appears, navigate to the following dialog:

User Configuration > Windows Settings > Internet Explorer Maintenance > Security > Authenticode Settings

You should see a dialog similar to this

Please verify that the "Enable trusted publisher lockdown" checkbox is unchecked. If checked, uncheck it and click OK.

Thanks,

Chris

Can you try "unblocking" the application using the steps outlined in this post?

I'm running Windows 7 Pro (64-bit)

I just had the exact same error, the following worked like a charm for me...

Download latest standalone installer and save to the root of C:

http://aihdownload.adobe.com/bin/install_flashplayer11x32ax_gtbd_aih.e xe

http://aihdownload.adobe.com/bin/install_flashplayer11x64ax_gtbd_aih.e xe

Download and run the Flashplayer Uninstaller

http://download.macromedia.com/pub/flashplayer/current/uninstall_flash _player_32bit.exe

http://download.macromedia.com/pub/flashplayer/current/uninstall_flash _player_64bit.exe

Install latest standalone version with elevated admin permissions - "holding <SHIFT> button down, right-click the downloaded file and 'run-as' another user, enter your local admin user creds, ie. administrator & Pa$$w0rd and installer will start".

http://www.dummies.com/how-to/content/how-to-run-a-program-with-elevat ed-permissions.navId-323054.html

Bounce machine (reboot!)

Browse to this link http://helpx.adobe.com/flash-player/kb/find-version-flash-player.html and confirm you are on the latest version.

Hope this helps someone!

Cheers,

John (UK)

I'm having this same issue, after unblocking the installer I just get an error that certificate authentication has failed and the program doesn't run. After unblocking I was finally able to run the uninstaller though and go back to an archived version 11.2.

That installer worked.

Any idea why the certificate was revoked though? Running win7 64bit.
