Is this SEP 12.1 or 11.x?

  1. Open the Windows Registry editor (regedit.exe) and browse to the following registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager
  2. 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:
  3. Right-click on the SessionManager registry key that contains the PendingFileRenameOperations value and choose Export
  4. Provide a file name and location for the exported registry key and click Save
  5. Delete the PendingFileRenameOperations value from the registry
  6. If HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update\RebootRequired exists, right-click on the RebootRequired registry key and choose Export.
  7. Provide a different file name than in step 4 for the exported registry key and click Save
  8. Delete the RebootRequired sub-key
  9. Install Symantec Endpoint Protection normally
  10. Before rebooting, double-click on the .reg files created in Step 4 and 7 to merge the previous PendingFileRenameOperations value and RebootRequired sub-key.

Delete the reg value PendingFileRenameOperations under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SessionManager\

Try the install immediately after deleting (do not reboot)

If that still doesn't work, post the SEP_INST.log file located in %temp% directory.

Please click the "Mark as solution" link at bottom left on the post that best answers your question. This will benefit admins looking for a solution to the same problem.

n the SEP_install log , search for return value 3 and paste 10-15 lines above that. Paste all instances of RETURN VALUE 3.

  1. In the registry, navigate to:

2. Back up the registry key.

3. Delete the PendingFileRenameOperations registry value from the right pane.

4. Install the software without restarting the computer first (Restarting the computer may result in the registry key being placed back in the registry before installation.)

5. Restore the registry key from the backup location.
