title: Updating version number in Add/Remove programs window
body: <p>We have an application consisting of various parts:</p>
  
  <ol>
  <li>A printer driver build with Inno-Setup.</li>
  <li>Custom written C# dll's.</li>
  <li>An AutoIt script, packaging and installing the previous two.</li>
  </ol>
  
  <p>The printer driver is listed in the Add/Remove section of Windows, with <code>[name]</code>, <code>[publisher]</code> and <code>[installed on]</code> fields displayed as expected. But the <code>[size]</code> and <code>[version]</code> fields are left blank.</p>
  
  <p>Our client wants us to update the <code>[version]</code> field. Where is this information stored (how to update or add this in the Add/Remove section of Windows)?</p>
