If you install to default dir, then install by:
running msmaster2.0.exe
running desktop.exe
double click bind ms (icon on desktop)
have psp connected when running bind ms


If you change the install dir...
after installing msmaster2.0.exe navigate to the install folder
enter "drivers" folder 
right click gui.exe and create shortcut (then copy it to the desktop)
right click install.exe and create shortcut (then copy it to the  desktop)
You need to run install.exe before msmaster will work properly.
