Event Id 2412 = 'Deployment Failed', which I suspect you already knew.
You should look at the local machine's ePO agent logs and the VirusScan install logs for more information about the actual cause, in this case on machine WP169.
dummy question ?
Where can I found those logs ?
Agent log will be under \Documents and settings\All Users\Application data\McAfee\Common framework\DB.
On Vista/Win7/2008 machines, it will be under C:\ProgramData\McAfee\Common Framework\DB.
VSE install log will be under Temp directory.
