How do I improve Chrome binary detection on Windows for Puppeteer?

Answer

To fix Puppeteer not finding the Chrome binary on Windows, make sure the detector checks the common install locations:

• Program Files\Google\Chrome\Application\chrome.exe
• Program Files (x86)\Google\Chrome\Application\chrome.exe
• %HOMEDIR%\AppData\Local\Google\Chrome\Application\chrome.exe

Here is a simple Windows path finder you can adapt:

const fs = require('fs');
const path = require('path');

function fileExists(p){ try { return fs.existsSync(p); } catch { return false; } }

function findChromeWindows(){
  const candidates = [
    'C:\\Program Files\\Google\\Chrome\\Application\\chrome.exe',
    'C:\\Program Files (x86)\\Google\\Chrome\\Application\\chrome.exe',
    '%USERPROFILE%\\AppData\\Local\\Google\\Chrome\\Application\\chrome.exe'
  ];
  for (const c of candidates){
    if (fileExists(c)) return c;
  }
  return null;
}

console.log(findChromeWindows());

This approach follows the common Windows installation paths and helps Puppeteer reliably locate the browser on Windows.
