Kurt_Aust, it seems you have the installer without JRE. I have the installer with JRE, because the Italian version of the installer without JRE doesn't exist. So using the installation file *with JRE* I want to do an installation without JRE, so I need to know which argument/option/parameter I can use in order to do that. Just as you can use /S to do a silent installation, I need the option to do the installation without JRE, something like this: OOo_2.4.1_Win32Intel_install_wJRE_it.exe /NOJRE
