title: SQL Server 2005 - install & setup -ADD_LOCAL property / template.ini / UPGRADE property
body: <p>I'm trying to install SQL Server 2005 Developer Edition on my Windows 7 Ultimate laptop.</p>
  
  <p>When the installation runs, I am getting the following error :-</p>
  
  <p>A component that you have specified in the ADD_LOCAL property is already installed. To upgrade the existing component, refer to the template.ini and set the UPGRADE property to the name of the component.</p>
  
  <p>I had installed an Express version from the Web Platform installer, but I'm sure I removed that. Also installed were compact editions from a mobile development workshop I did last year. I removed those also.</p>
  
  <p>Currently my Uninstall or change a program list in Control Panel has the following SQL Server related entries :-</p>
  
  <ul>
  <li>Microsoft SQL Server 2005</li>
  <li>Microsoft SQL Server 2005 Backward Compatibility</li>
  <li>Microsoft SQL Server 2005 Books Online (English)</li>
