title: Removing bad installs from Add/Remove programs
body: <p>I've created a custom boot-strapper for my application using Wix and Burn, but in the time it took to learn I managed to install several early variants in such a way that they won't uninstall.  I think I created the problem by running Engine.Apply before PlanComplete had been called.</p>
  
  <p>Where is the information that builds the list in Add/Remove programs and what is the best way to manually remove orphaned rows?</p>
  
  <p><strong>Update</strong> - I should have said I'm on 64 bit Windows 7 Enterprise, Service Pack 1.</p>
