title: Multi-part Windows installer version numbers
body: <p>I've noticed that some programs installed on Windows have more than three numbers in their versions. The installer creation software vendor that I use claims in their support forum that Windows Installer only uses three numbers (like <code>major.minor.patch</code>).</p>
  <p>My question is, how do these other installers set different formats?
  Some even have rather wacky date-like values embedded in them.</p>
