I think it should be no problem to install McAfee agent on 2008 R2. Though I am not using McAfee antivirus product, I think it should be working on 2008 R2, so I think McAfee agent should be working on 2008 R2 too. But even I did not get any install error, I cannot see the McAfee agent tray icon. I installed it from EPO console, action "New System"->"Push agents and add systems to the current group (my group name)".
I deployed DLP agent from console, and I can see the DLP agent tray icon.
The problem is everything looks ok, I can see the server in EPO console system tree, and I can see the communication logs without error. But 2 things are not normal and expected. One is I cannot get the right click menu from McAfee agent tray icon, for there is no this tray icon. There is no Mctray.exe running in memory, and after I called it manually I could not see the tray icon either. One details is Mctray.exe what I called manually was running in 32bits mode, but other atuorun ones were in 64bits mode. Another is the DLP agent is in status of "Agent is running in device control and content aware removable storage protection mode", even I set it as "Device control and full content protection" in agent configuration. I have restarted server to make sure the setting applied, but no change.
One details is the server on which I insatlled DLP agent is for running descovery rules, and there is Agent Handler installed on it.
Is what I faced by design?
I install the McAfee agent and DLP agent from EPO console.
EPO version: 4.6.6
DLP version: 220.127.116.11
I checked the processes on a 64 bits win7 pc, Mctray.exe is running in 32 bits mode, and all other processes runnning under 64 bits mode too. So I think process bits is not the reason.
Thanks for you in advance.
McAfee agent is work on 2008 R2. But it has a problem with display the icon in tray:
Thanks, solution in KB is working. And do you have any idea about 2nd problem?
BTW, do you know if I can mark more than one post as "Correct Answer" or "Helpful Answer"? I am afraid if I mark yours as answer no one will check this topic for 2nd problem. I knew it is my fault put two question in one topic, but from begging I thought maybe they were linked to same reason.
Quick reference for other: solution for no McAfee tray icon is call UpdateUI.exe manually. For details, check link posted by bible2008 above.
I marked bibl2008's answer as correct answer for my first question. I will create a new one for my second question.
Thx for all of you.
