I've been reading back through this thread but I can't seem to find the solution for installing Coderus' system ui properly. I'm still getting the permission denied errors, even when I make the status-menu folder myself.

I can install all applets using the method Schturman wrote earlier, but really I only want the battery icon and percentage shown at the same time like thedead1440's. Installing all applet gets rid of the icon, so I can only seem to have one or the other atm. Any ideas?
