many thanks Denis i appreciate a lot your help and will try your solution.
I would appreciate also the second solution you promised to propose for 
this feature:)

also Dennis, i wanted to ask if using a processpanel is the best way to 
automate openoffice exe installer?
well i did that and this is working how ever i have an issue that i need 
to solve:

if user doesn't have oo and choose to install it then i'm launching the 
oo_instller.exe from izpack process panel .how ever in this way i loose 
all control on the other installation wizard of oo installer ..so i 
wonder how i would know the path the user selected to install oo. (i 
need to save this path in a properties file)
well if the oo_installer.exe sets some environment variable holding oo 
home folder then i can write a small java class to get this variable 
.but the question : does the oo installer sets some variable of that kind ?
otherwise i don't see how we can know the target oo path .
what u think ? do you have an idea ?
