Puppeteer fails to launch on Windows

Steps to reproduce

• Puppeteer version: 1.12.2
• Platform / OS version: Windows 10 / 1809
• Node.js version: v11.6.0

1. await puppeteer.launch()

  Error {
    code: 'UNKNOWN',
    errno: 'UNKNOWN',
    syscall: 'spawn',
    message: 'spawn UNKNOWN',
  }

1. Running chrome.exe manually

The application has failed to start because its side-by-side configuration is incorrect. Please see the application event log or use the command-line sxstrace.exe tool for more detail.

I’m not sure this is a Puppeteer/Chromium bug

Sometimes if I copy chrome-win manually into node_modules\puppeteer\.local-chromium\win64-624492 I get that error too. So I believe its Windows fault, just not sure what to do with such information… This occurs randomly.

Don’t know if it’s related to the initial issue or not, but having the same problem (same error from chrome.exe), I realized in my case it is caused by the project folder having the case sensitive attribute enabled.

Fixed it by running fsutil.exe file setCaseSensitiveInfo . disable in the project folder, then reinstalling dependencies
