  1. Go to the following registry keys,

    and ensure the logged in account used under the updating policy has full access permissions.

  2. Restart the computer. On the Sophos shield in the system tray, click 'Update Now'.

Technical Information
Browsing to C:\Program Files\Sophos\AutoUpdate via Windows Explorer will result in the following message:

C:\Program Files\sophos\AutoUpdate is not accessible

The folder has been set to 'Read-only', manually changing this to full access and then applying changes will just reset it back to 'Read-only'.
