Error: wine: Bad EXE format

electron-winstaller@2.6.3 windows 10, 64-bit.

Cant build setup.exe with error:

Failed with exit code: 4294967295 Output: System.AggregateException: One or more errors occurred. —> System.Exception: 7-Zip [64] 16.04 : Copyright © 1999-2016 Igor Pavlov : 2016-10-04

Then I decided to get squirrel logs with set DEBUG=electron-windows-installer And got these messages from node_modules\electron-winstaller\vendor\SquirrelSetup.log:

Utility: Failed to extract file /var/folders/sj/rrk8jvvj74j_mmjgcw505h5w0000gn/T/ei-11755-93846-r5wfhu.s4dlf5stt9/myapp.1.0.0.nupkg to /Users/kevin/.local/share/SquirrelTemp/tempa err:process:create_process 64-bit application L"Z:\Users\kevin\github\windows-installer\vendor\7z.exe" not supported in 32-bit prefix wine: Bad EXE format for Z:\Users\kevin\github\windows-installer\vendor\7z.exe.

Could anyone explain what happened?

@thre-isdd This is not a solution, but here how I managed to make it work.

1. downloaded 7-zip 32bit at http://www.7-zip.org/a/7z1604.exe
2. installed it via wine
3. copied .exe and .dll from .wine/drive_c/Program Files/7-Zip to electron-winstaller/vendor

@paulcbetts , is there any reason why the 7z.exe is in 64 bit format? I guess that the 32 bit version would also work in x64 machines and would not suppose a problem when building 32 bits applications.
