title: How to set default installation dir for MSI?
body: <p>Using VS2010.  I have a VS Installer project.  I've <a href="http://web.archive.org/web/20120419133515/http://msdn.microsoft.com/en-us/library/h0z89y5d.aspx" rel="nofollow">learned</a> how to set the default install dir according to a registry value.</p>
  
  <p>But, I need to add logic so that if there is no such RegKey, then fall back onto the default [ProgramFilesFolder][Manufacturer]\[ProductName] as the default install dir.</p>
  
  <p>Hoping to not need WiX for this (due to time constraints and learning curve).</p>
  
  <p>This is my first post.  Please correct me if I haven't followed the guidelines.</p>
  
  <p>Thanks.</p>
