Hey, from my comment #2683 (comment)

This issue appears inside electron-winstaller
electron/windows-installer#386

I had the same issue but it's fixable manually.

1. Open ./node_modules/electron-winstaller/vendor
2. Copy 7z-x64.* files as 7z.* (fe, 7z-x64.exe => 7z.exe)
3. Try to build it again

Building squirrel installers from macOS isn't supported in macOS versions that have dropped 32bit support. This can be tracked upstream in the Squirrel repo if you're interested.

Forge recommends building for a platform, on that platform. i.e. host === target
