Hey This issue appears inside electron-winstaller https://github.com/electron/windows-installer/issues/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

If you want to build a windows app on Mac or Linux OS, you need to install wine and mono. In your case, the mono is missing.

Same problem building on Windows 11.

I was running into this same issue on MacOS Monterey 12.3.1 on my MacBook Air (M1, 2020).

After installing mono I get past the above mentioned errors, but it seems to hang on:

Electron version: 16.2.8 Electron force version: 6.0.0-beta.64

It's been running for 15 minutes now with no changes... gave up and switched to electron-builder which just seems to work without installing anything extra.
