I have Agent 188.8.131.520 connecting to an ePO 4.0 server. After updating the Agent to that 'built' on an ePO 4.5 server, the 'Update Security' will only update DAT and Engine - not Patches (VirusScan, HIPS etc). Both DATs and Patches are set to update in the Update task.
Any ideas? I have removed and reinstalled the Agent - same thing.
