@cadetsparklez ,

The error message asked if the command was correct. Is it?

Is that where your Notepad++ installation is? Does that file really exist at the exact path shown?

If you run Notepad++ normally, rather than through context menu, does it run correctly? Can you share Notepad++'s ?-menu’s Debug Info (you can copy/paste the text from that dialog, because sometimes the text is more than fits in the visible dialog, so a screenshot will cut things off).

Yeah the path looks correct, the error message has quotes in the command so that should be ok with there being a space in the path, although in the debug info there is not.
