Problem computer: Windows Vista computer.
Problem: Symantec Endpoint Protection (SEP) Installation fails with the following error “Symantec Endpoint Protection has detected that there are pending system changes that require a reboot. Please reboot the system and rerun the installation.”
Solution: I rebooted the computer several and got the same result each time.
I found the registry key entry that I used to fix the problem.
Delete the registry key
Install the software without restarting the computer
NOTE: If you are running Windows Vista look for this key – HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet001\Control\SessionManager\PendingFileRenameOperations
