Inno Setup is a popular installer builder for Windows. Of course it is made to run on Windows only, by default. But what if you want to build Windows installers off Windows, i.e. on Linux or macOS?
You’re in luck: It’s possible to run Inno Setup anywhere that Docker runs (including Linux and macOS), and even have a passable experience writing your setup script.
