To create a silent install, run setup.exe -r
Setup.iss gets created in C:\windows

Copy that to your source folder and run
  setup.exe -f1"path to setup.iss"\setup.iss -s
Make sure there is no space between f1 and the quotes to your path to setup.iss

You can create a silent uninstall using the same method.
