title: Inno setup a simple update
body: <p>Is it possible to use same Inno Setup installer for installing new or updating/upgrading application. For example If the application is already installed the installer will check current version against newly availible. If it is true then I would like the installation procedure to be silent, meaning showing only the progress of update and not all availible installation features (e.g. folder location e.t.c). Thanks.</p>
