After a new installation of Deployment Solution 7.1 (either upgrade from 7.0 or clean install) the '<Program Files>\Altiris\Altiris Agent\Agents\Deployment\Task Handler\' folder is missing files and/or folders from the directory structure.
The correct default contents of the 'Task Handler' folder should look as follows:
This was likely caused by an issue with installation packages during the installation through the Symantec Installation Manager.
A manual run of the installer will correctly build the directory structure and populate it with the necessary files. The installer package for these items should have been downloaded if the Altiris Deployment Solution product was selected to be installed from the Symantec Intallation Manager (SIM).
We've also found an issue where the WMI is damaged which will prevent a complete installation - actually it will roll-back the installation of the Task Handlers, leaving only the WAIK installed. Please see TECH142575 for more information.
