Those annoying CAPI2 errors

On August 22, 2010, in Security, by

Now trying this:

The Root Certificates Update component downloads a cabinet (.cab) file to the temporary directory on the local computer, extracts the contents of the file, and then updates the root certificate list. It is possible there are corrupt files in the temporary directory. By default, the temporary directory is located at %userprofile%\AppData\Local\Temp. 

Please go to an affected workstation, clear the content of the temporary directory.

 In addition, the correct permissions must be applied to the temporary directory in order for the cabinet file to install correctly:

 Navigate to %userprofile%\AppData\Local\Temp.

  1. Right-click the temporary directory, and then click Properties.
  2. Click the Security tab.
  3. Ensure that the user account logged on to the computer has Full Control permissions.


 Event ID 11 — Automatic Root Certificates Update Configuration

 Then check if the error still occurs.

To see if it gets rid of this:

This didn’t work.  Still searching for what this is, why this is, still for now, try to ignore this.

    I have had those CAPI2 errors continually for over a year on an SBS2008 machine, and cannot get rid of them. I’ve tried numerous recommended solutions, including the above one, and… no luck. Looking forward to seeing if you have any more success than I’ve had.

    I’m so glad you wrote that 2nd article. I’ve tried several things after you wrote the first one regarding that issue. All without luck. Almost thought I go crazy seeing that Capi2 errors ever and ever again…
