Windows installer
godot.iss is an Inno Setup installer file that can be used to build a Windows installer. The generated installer is able to run without Administrator privileges and can optionally add Godot to the user's PATH environment variable.
To use Inno Setup on Linux, use innoextract to extract the Inno Setup installer then run ISCC.exe using WINE.
Building

godot.exe.Run the Inno Setup Compiler (part of the Inno Setup suite) on the
