I have a javafx application which I package it with javafx-maven-plugin (windows installer). I could also package it with ANT script.
My question is, I could change the Icon of the installer. But is it possible to change the install wizard style? like button colors, caption, add a logo, background image, etc?
There are several 3rd party components which allows to change the design of Inno Setup installer.
The most well known and officially recommended (http://jrsoftware.org/is3rdparty.php) by Inno Setup are:
1) Graphical Installer (http://www.graphical-installer.com) - extension that allows to customize almost every aspect of installer (background, buttons, icons, fonts, colors, ...). Commercial plug-in (I was personally involved in development):
2) VCL Styles for Inno Setup (https://github.com/RRUZ/vcl-styles-plugins/wiki/Inno-Setup) - free and Open Source plugin (dll) that allows you to add skins to the Inno Setup installers.
3) ISSkin (http://isskin.codejock.com/) - free version of Codejock’s Skin Framework that allows add customized skins to installer.
