The error 1618 usually means that there is another installation “already in progress”. Now this doesn’t always mean that there really is one in progress, but there may still be a “PendingFileRenameOperations”. In my task sequence, I have a reboot occur after the installation of “McAfee EPO Agent 4.6” as well as a reboot after the install of “McAfee Virus Scan Enterprise 8.8.02004”.
A quick way to verify if indeed a reboot is needed in between would be to check for the existence of the following registry key after the “McAfee EPO Agent 4.6” is installed:
PendingFileRenameOperations (If this exists, then it is a good bet that you need to reboot the computer before trying to install anything else)
Also, you if desired you can copy the code below and paste it into a VBS. This will help to determine if a reboot is required. I have used it in the past for patches, but should work as well for packages.
================= Copy Below =================
Set objSysInfo = CreateObject("Microsoft.Update.SystemInfo")
Wscript.Echo "Reboot required: " & objSysInfo.RebootRequired
