Installer-wizard Memes

You just wanted to install one simple program, but now Windows is throwing random error messages at you like an NPC with a broken dialogue tree. "An error occurred. The Wizard must be stopped." Sounds less like a helpful installer and more like the final boss fight you didn't sign up for. The best part? The error message tells you absolutely nothing useful. What error? Which wizard? Why must it be stopped? These are questions that will remain unanswered as you frantically Google the message, only to find three forum posts from 2009 with no solutions. Welcome to the side quest nobody asked for: debugging Windows installers. Reward: maybe your software works. Maybe.
