So I'm trying to make an application install without any user input but I can't get it to work.
I've created the setup.iss using setup.exe /r and had no problem with it.
However when I deploy it with setup /s /v/qn it does not install silently, instead it shows a couple of dialog windows (but some are hidden so it uses the iss-file) where I have to click next, next, install. Everything is correctly filled in but it refuses to install silently.
I've checked the %Temp% directory when I launch the setup.exe and there is a directory with ISScript11, Application.msi, Application.mst and a bunch of ini-files. I can't install the msi directly because if I try to run it it shows no dialog windows so it seems like this msi is dependant on setup.exe.
I decided to repackage the application and it worked just fine. I would have preferred to use the original setup.exe but I suspect that the application developer missed some stuff when he made the installshield setup.
