how to how to..

i had installed the autocom ppc software into sdcard of the Diagun tool.
but when try to install manual ( automatic doenst start) from folder 2577, its asking the ID, accepted, start,load agreement pdf but after few seconds shut off .
no icon on the desktop, if click on 2577/autorun_software.exe , the same thing, installer starts but stop.

is the diagun system files readonly?
