To prevent the uninstallation of McAfee ePO agent when installing or upgrading OfficeScan client:

On the OfficeScan server, go to the ..\Program Files\Trend Micro\Officescan\PCCSRV\Admin folder.
Look for and back up the tmuninst.ptn file.
Open the file using a text editor like Notepad. Comment out the entries below with a semicolon (;).
Here is a sample:
;[ePOAgent1000]
;ProductKey = HKEY_LOCAL_MACHINE\SOFTWARE\Network Associates\ePolicy Orchestrator\
Application Plugins\ePOAgent1000
;UninstallKey = HKEY_LOCAL_MACHINE\SOFTWARE\Network Associates\ePolicy Orchestrator\
Application Plugins\ePOAgent1000
;Platform = Win95 | Win98 | WinNT
;UnloadProgram = GenericUnload
;UninstProduct = UninstVirusScan45
;Support = 1

;[ePOAgent2000]
;ProductKey = HKEY_LOCAL_MACHINE\SOFTWARE\Network Associates\ePolicy Orchestrator\
Application Plugins\ePOAgent2000
;UninstallKey = HKEY_LOCAL_MACHINE\SOFTWARE\Network Associates\ePolicy Orchestrator\
Application Plugins\ePOAgent2000
;Platform = Win95 | Win98 | WinNT\
;UnloadProgram = GenericUnload
;UninstProduct = UninstVirusScan45
;Support = 1

;[ePOAgent3000]
;ProductKey = HKEY_LOCAL_MACHINE\SOFTWARE\Network Associates\ePolicy Orchestrator\
Application Plugins\ePOAgent3000
;UninstallKey = HKEY_LOCAL_MACHINE\SOFTWARE\Network Associates\ePolicy Orchestrator\
Application Plugins\ePOAgent3000
;Platform = Win95 | Win98 | WinNT
;UnloadProgram = GenericUnload
;UninstProduct = UninstVirusScan45
;Support = 1
Save and close the file.
Restart the OfficeScan Master Service.

If there are any other McAfee programs that require McAfee ePO Agent, this solution also works in preventing automatic uninstallation of McAfee ePO Agent during OfficeScan client installation or upgrade.
