I keep getting certificate authentication failed error message trying to install Flash.  I am using OS Win7Pro on a stand alone desktop using IE9 version 9.0.8112.16421 256bit.  This is happening with the Adobe Flash and the Adobe Shockwave Player.  I am able to download the files and save them to my downloads folder.  I will right-click to select install as an administrator using my user account with admin privileges.  Any ideas which may be causing this?

Przemek, this is the same exact post I made earlier today, but it is not listed under my profile anymore.  It is like you somehow stole the post and posed it like it was your question.  Did you do that to steal points???   I actually came back on the site to inform people I fixed it by manually installing the Adobe ActiveX from http://helpx.adobe.com/flash-player/kb/installation-problems-flash-player-windows.html and then changing a setting called TURN OFF AUTOMATIC ROOTS CERTIFICATE UPDATE to not configured in the Group Policy Editor.  You can access the Group Policy Editor by typing Group Policy in the start menu search box of Win 7 and then click on the link for Group Policy Editor in the search results.  From there, you click on ADMIN SETTINGS and then ALL SETTINGS to find the option.   I hope this helps people, but I am not quite sure what your point in stealing my post was Przemek.

It is the forum software/servers that are acting acting weird for the last few days.  Ignore it; it will eventually settle back to normal.

Hi Warren,

 

If you're still encountering the 'certificate authentication failed' error when downloading/installing from get.adobe.com/flashplayer, please try one of the following two options:

Option 1:

  1. Open command prompt (C:\Windows\System32\cmd.exe)
  2. At the prompt, type: Certutil –urlcache * delete

Option 2:

  1. Delete the contents of the “temp” directory (on Win7 - C:\Users\<YourUseID>\AppData\Local\Temp)

Thank you.

Run Windows Update and let it fix your certificates.
