如何对使用WiX install构建的安装集(MSI)进行重大升级，将其与原始安装安装在同一文件夹中？

已正确检测到该安装是升级，但仍显示目录选择屏幕，并带有默认值(不一定是当前安装文件夹)。

我是否需要做手动工作，例如在首次安装时将安装文件夹保存在注册表项中，然后在升级时阅读此项？如果是这样，有什么例子吗？

还是有一些更简单的方法可以在MSI或者WiX中实现呢？

作为参考，我当前的WiX文件如下：

WiX教程中有一个示例：http://wix.tramontana.co.hu/tutorial/getting-started/where-to-install

<Property Id="INSTALLDIR">
  <RegistrySearch Id='AcmeFoobarRegistry' Type='raw'
    Root='HKLM' Key='Software\Acme\Foobar 1.0' Name='InstallDir' />
</Property>

当然，我们也必须在安装过程中设置注册表项。将其粘贴在原始安装的一部分内的组件中：

<RegistryKey
         Key="Software\Software\Acme\Foobar 1.0"
         Root="HKLM">
  <RegistryValue Id="FoobarRegInstallDir"
             Type="string"
             Name="InstallDir"
             Value="[INSTALLDIR]" />
</RegistryKey>
