Sophos Enterprise Console on Windows Server Essentials 2012

Hi,

I recently installed a new Server Essentials 2012 setup and installed Sophos Enterprise Console 5.2.1.97. I am unable to protect any of the computers from the central console despite creating a group policy to open ports 8192 and 8194 and set services (Windows Installer - manual, Task Scheduler - Automatic, Remote Registry - Automatic).

I've run through all the documentation and every time I try and push out the software to Windows 7 clients I receive the error:

21/11/2013 10:00:55 80070002 The installation could not be started: The system cannot find the file specified. The computer may need additional configuration before installation. See knowledgebase article 29287.

I've already installed the Endpoint Security on the clients but cannot get the console to manage them.

Any advice would be appreciated.

Thanks
