The /S /v/qn is supposed to be a silent install, but it isn't. At least not for me. You still have to click 'Next' on the first initialization dialog. Does anyone know? iTunes 4.7 doesn't generate the setup.iss file using the -R switch either, (4.6 did..) and after installing it, in the log-file, it says 'error 3' or something, which means it cannot find enough info in the setup.iss file. I got the 4.6 version to work, but not 4.7...
