title: How to debug an electron app packaged with squirrel that won't start on some computers
body: <p>I've built an Electron app using the Squirrel packager/update manager.
  I've had no issues in building the bundle, targeting Windows 64bits only.</p>
  
  <p>I installed it on my Macbook pro (on a windows 7 x64 dual boot) without trouble. I tested it also on a 64 bit Surface pro 3 (Win 10), and another Win 7 PC. Everything works fine.</p>
  
  <p>I published the app and got a few hundred downloads :half the people that downloaded it has it working, and for the other half it just won't start. The process spawns, then dies a second after. I tried starting it in admin, the admin dialog box won't even show. I tried running it from command line </p>
  
  <pre><code>myapp.exe &gt; out.txt
  </code></pre>
  
  <p>But out is empty. How can I debug this ?</p>
