How to Clear Require Reboot Errors for Symantec EndPoint Protection Installer

In Windows 7 O/S workstation when attempting to install the Symantec EndPoint Protection client on the workstation and constantly receive the following error message:  “Symantec Endpoint Protection has detected that there are pending system changes that require a reboot.  Please reboot the system and rerun the installation.”

Even though, the system has been rebooted and even shut down numerous times and I still receive this error message.  Here is how I fix when I had that issue.

1. In Task-Manager end all processes that starts with msiexec.exe.

2. Open registry and go to

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\

hight light Session Manager on the right hand side delete the value


Also delete the same value from

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet001\Control\Session Manager\PendingFileRenameOperations

then run the install…without rebooting the PC.
