it uses a ZIP SFX, after extracting it i found a setup.exe and bdprof.msi. i will use the /QB! switch to make the silent install (i haven't test it yet but it is supposed to work). the problem it's that i don't know how to register it once installed. i've found in my registry:

[HKEY_CURRENT_USER\Software\Softwin\BitDefender Desktop 7\Maintenance]"ProductCode"="{X-X-X-X-X}"

but i think this only mess with the msi installer. maybe the key it's on the BD dir, isn't it??

i really want to install this software silently. nowbody have replied. any ideas??

The registration is at the end of win.ini : weird, unsafe and dirty... looks like they sort of wanted to hide it...

You can't append the section directly via echo : you must append it using the copy command in binary mode...

You can even update it automatically using wget and 7-Zip...

until now i haven't been able to do test it and works!! thanks
