i dont understand installrite, but ok i will spend more time on installrite to learn how to work....... edit: i get the next switches by typing /help /help, /language=, /loglevel:,/nocancel,/nolicence,/noreboot,/no_ui,/path=,/silent,/sn=<serialnumber>,/write_sn type un.exe/languagepack=dutch /noreboot /silent /sn=XXX wont help also i think the problem is the silent switch, when not using silent it will works perfect, but then it isnot unattend anymore
