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 (c) 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

wine: Bad EXE format for Z:\Users\kevin\github\windows-installer\vendor\7z.exe.

Could anyone explain what happened?
