I downloaded hot fix 1174804 to the server I have ePO on and tried manually installing it using the FramePkg_upd.exe. It looks like it installed successfully but I can't find anywhere/anything that shows McAfee Agent is now version 188.8.131.529. My Software Manager shows my Agent at 184.108.40.2063. How do I know the install really did anything? It said it was successful.
The easy way is to see in About, right click on the shield of mcafee, you choose about and there it tells you that version of agent you have installed, although in the EPO another appears, but that is already subject of sending events
On that server there is no McAfee Agent shield just a VirusScan shield. On my PC it still shows the old version number but it's possible the Agent just hasn't synced yet.
The McAfee Shield not showing is pretty common and can be forced to show by running - "C:\Program Files (x86)\McAfee\Common Framework\"cmdagent.exe /s
Make sure to run that in an admin CMD and it will bring up the Agent Monitor which will populate the Agent icon in the tray. You can also run the UdaterUI.exe in that same file path.
