Unable to open Symantec Installation Manager (SIM).
Getting a Windows error when trying to open SIM. "Another installation is requiring a reboot to complete changes to the system. You must reboot your computer before you can use Symantec Installation Manager, then Launch Symantec Installation Manager again."
There is a value left in a registry key that is trying to make changes to the system but upon reboot these changes are not made and remain in the registry. Most likely there is a driver that has not finished loading. Looking at the PendingFileRenameOperations data will determine what is causing the issue.
