The workaround to resolve the error mentioned above is to reset the KADE installation. This article explains how to clear up the Windows Registry to reset the KADE installation.

 

 

Preconditions

The Kerio Active Directory Extension should be installed.

 

 

Root Cause Analysis

The registry corruption occurs during the Windows server migration. This can block a successful KADE upgrade.

 

 

Workaround

  1. Create a backup of the system, including the registry.
  2. Open the Registry Editor.
  • Go to Start > Run > type regedit > hit Enter.
  • Go to HKEY_CLASSES_ROOT.
  • Find the key(s) related to the Kerio AD extension installation:

    NOTE: The exact key varies depending on the version installed. In the latest versions of the Windows server (2016 and 2019), the registry key might be located in the HKEY_CLASSES_ROOT\Installer\Products\ folder.
  • Once you locate the correct folder, delete it.
  • Run the installation wizard (as instructed in the Preconditions section above) for the new version.

    Confirmation

    The KADE is successfully upgraded to the latest version now.
