Squirrel.Windows maker: setupIcon config not working

The documentation states you can change the icon of the Setup installer application using the setupIcon option. It doesn’t seem to do anything. The iconUrl option works however, even when they are pointed to the same resource.

@malept TL;DR Read my Edit at the bottom of this comment for solution I found.

I am having the same difficulty with setupIcon. Could someone please post a very obvious example of the final path? Like what does a absolute setupIcon path should look like?

I’m trying all of the above examples and it never finds the image path (Fatal error: Unable to load file).

Here’s what I’m doing (and I’ve tried atleast 30 variations)

    'makers': [
        {
            'name': '@electron-forge/maker-squirrel', //https://js.electronforge.io/maker/squirrel/interfaces/makersquirrelconfig
            'config': {
                'name': 'Finance-D',
                'setupExe': 'Finance D - Installation.exe',
                'setupIcon': path.join('resources', 'app', 'src', 'images', 'favicon.ico'),
            }
        },

output directory structure: source directory structure:

Where is the maker-squirel module looking at. I don’t understand why it fails with even absolute paths and relative, etc.

EDIT: I found a hidden property somewhere on the internet and it fixes the problem! It’s unexpected but adding the skipUpdateIcon:true property in the configs will work even for the same exact setupIcon path… wierd. So, I’m refering to this https://js.electronforge.io/maker/squirrel/interfaces/makersquirrelconfig#setupicon and my solution right now is:

    'makers': [
        {
            'name': '@electron-forge/maker-squirrel', //https://js.electronforge.io/maker/squirrel/interfaces/makersquirrelconfig
            'config': {
                'name': 'Finance-D',
                'setupIcon': path.join(__dirname, '/src/images/favicon.ico'),
                'skipUpdateIcon': true,
            }
        },

I can’t reproduce this behavior. I have a testcase here: https://github.com/malept/electron-forge-demo123/tree/forge6-issue-1635

I had GitHub Actions build a Squirrel installer here: https://github.com/malept/electron-forge-demo123/actions/runs/116519042

It shows the correct icons both when I run the setup file and when I uninstall the app.

If you can provide a minimal testcase repository that shows the behavior you describe, please link it here and we can see if it is a bug in Electron Forge (or more likely, if it’s a bug, it’s in electron-winstaller or Squirrel.Windows).
