thanks for the reply guys..

But I didn't mean to open / execute the exe file, just want to dowload and save it on my hard disk.. thats all.. maybe it becouse read only , like marhleet said..

Does anyone know how to solve problem no.1 ?

btw, when I try to browse my network I got this error massage :

" The lisa daemon does not appear to be running.
In order to use the LAN Browser the lisa daemon must be installed and activated by the system administrator "

What is it mean ?? what is Lisa daemon ??

Thanks..
