ok then no frontends!

I tried to disable every sound emulation system, and to mount a new empty dir.... but nothing, it does the same thing: as soon as I type install, it closes doxbox

here is the stdout file:
DOSBox version 0.72
Copyright 2002-2007 DOSBox Team, published under GNU GPL.
---
CONFIG:Loading primary settings from config file C:\Programmi\DOSBox-0.72\dosbox.conf
MIDI:Opened device:none
Exit to error: CPU:GRP5:Illegal Call 7

Sorry - I have no idea then.

I think it's a bug in Dosbox, perhaps the developers will read this and see
