NPE does not display even though according to "Task Manager" it is running; and I cannot start another NPE because it is running

NPE does not display activity when it is running even though "Task Manager" indicates it is running; and I can not start another session of NPE because I receive an error indicating another session of NPE is already running.  And, I can not shut down NPE normally because it never shows the "finish/end" display.  So I just guess, according to "Task Manager", when NPE has finished!  What the hell am I doing incorrectly?

Thank you,

Hi Leslie Funk Jr. ,

Are you still facing the issue, After following F4E comments if so please revert.

Hi. Are you running Windows 10 ? If so, it needs to be completely shut down for Norton and other programs to operate correctly.

Also, why did you run NPE ? It's a powerful tool that can delete critical system files if not used properly.

Do you think you may be infected ?
