title: Can I use AppId created by "Generate GUID" option in Inno-Setup?
body: <p>This is the first time when I'm in need of making a setup, so using Inno-Setup. But one thing I'm unable to find in the documentation that is the "Generate GUID" button really generates globally unique ID?? Can I use this as AppId of my app for production purpose??</p>
  
  <p>If yes then how it guarantees that it will be unique for production globally?
  I mean is this "Generate GUID" feature tracking all software's AppId in the world to make next one unique, or its generating it using the files being packed into the setup??</p>
