When attempting to launch Symantec Installation Manager the message is displayed: "...has detected that there are pending system changes that require a reboot. Please reboot the system and rerun the installation." This can also cause a reboot loop that never allows SIM to launch.
"...has detected that there are pending system changes that require a reboot. Please reboot the system and rerun the installation."
This is caused by pending reboot entries in the registry, whether valid or not.
The PendingFileRenameOperations registry value can be backed up and deleted. Symantec Installation Manager can then be launched, and the PendingFileRenameOperations value can then be replaced in order to facilitate launching without affecting the operating system or 3rd party applications negatively. This method will leave several temporary installation files in the logged-in user's temp directory that would normally be deleted after a reboot.
Open the Windows Registry editor (regedit.exe) and browse to the following registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager
Verify the following Reg Multi String value PendingFileRenameOperations exists under this key. Note: If you do not find the PendingFileRenameOperations value in the location above, this error message can be generated if there are pending changes in: HKEY_LOCAL_MACHINE\SYSTEM\ControlSetXXX\Control\SessionManager\PendingFileRenameOperations
Right-click on the SessionManager registry key that contains the PendingFileRenameOperations value and choose Export
Provide a file name and location for the exported registry key and click Save
Delete the PendingFileRenameOperations value from the registry
If HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update\RebootRequired exists, right-click on the RebootRequired registry key and choose Export.
Provide a different file name than in step 4 for the exported registry key and click Save
Delete the RebootRequired sub-key
Launch SIM and run the necessary processes.
Before rebooting, double-click on the .reg files created in Step 4 and 7 to merge the previous PendingFileRenameOperations value and RebootRequired sub-key.
