The purpose of Hexe is to rebrand executables compiled with NodeJS (like: nexe, pkg, electron) in a simple manner. It is a GUI that uses Electrons "rcedit" in the background.
The easiest way to setup and use Hexe is with the installer from here. Since the installer file is not signed you can alternatively download the resources as a zip-archive. Run "H.exe" after extracting it.
Using a websites favicon as icon for the executable is not enough. It won´t scale correctly. Therefore the icon must contain multiple sizes. If you are not yet familiar with such icons, please search on the internet to find out how to create them.
When you apply your changes the executable will be renamed according the value of "OriginalFilename". So better check twice that the value of this field is set correctly.
