Iis 默认网站下的wix虚拟目录未卸载，与其他功能冲突？

我正在为几个.net web应用程序使用wix构建一个安装程序。我有两个功能，其中一个在IIS的默认网站下安装多个虚拟目录/应用程序。第二个特性创建了一个单独的网站，其中包含一个虚拟目录

<ComponentGroup Id="IIS_Feature1">
  <Component Id="IIS_WebApp1" Guid="some-guid-1" Directory="wwwrootdir" KeyPath="yes">
    <iis:WebVirtualDir Id="WebApp1VirtualDir" Alias="webapp1" WebSite="DefaultWebSite" Directory="WEBAPP1DIR">
      <iis:WebApplication Id="WebApp1IISApplication" Name="webapp1" />
    </iis:WebVirtualDir>
  </Component>

  <Component Id="IIS_WebApp2" Guid="some-guid-2" Directory="wwwrootdir" KeyPath="yes">
    <iis:WebVirtualDir Id="WebApp2VirtualDir" Alias="webapp2" WebSite="DefaultWebSite" Directory="WEBAPP2DIR">
      <iis:WebApplication Id="WebApp2IISApplication" Name="webapp2" />
    </iis:WebVirtualDir>
  </Component>

  <Component Id="IIS_WebApp3" Guid="some-guid-3" Directory="wwwrootdir" KeyPath="yes">
    <iis:WebVirtualDir Id="WebApp3VirtualDir" Alias="webapp3" WebSite="DefaultWebSite" Directory="WEBAPP3DIR">
      <iis:WebApplication Id="WebApp3IISApplication" Name="webapp3" />
    </iis:WebVirtualDir>
  </Component>

</ComponentGroup>

<ComponentGroup Id="IIS_Feature2">
  <Component Id="IIS_WebApp4" Guid="some-guid-4" Directory="wwwrootcustom" KeyPath="yes">
    <iis:WebSite Id="WebApp4Site" Description="Web App 4 Site" Directory="wwwrootcustom" AutoStart="yes">
      <iis:WebVirtualDir Id="WebApp4VirtualDir" Alias="webapp4" Directory="WEBAPP4DIR">
        <iis:WebApplication Id="WebApp4IISApplication" Name="webapp4" />
      </iis:WebVirtualDir>
      <iis:WebAddress Id="WebApp4SiteAddr" Secure="yes" Port="443"/>
    </iis:WebSite>
  </Component>
</ComponentGroup>

问题是，当我安装这两个功能时，默认网站下的虚拟目录（来自功能1）在卸载过程中不会被删除。奇怪的是，如果我只安装功能1（排除功能2），卸载功能1会正常工作，虚拟目录也会被删除

<ComponentGroup Id="IIS_Feature1">
  <Component Id="IIS_WebApp1" Guid="some-guid-1" Directory="wwwrootdir" KeyPath="yes">
    <iis:WebVirtualDir Id="WebApp1VirtualDir" Alias="webapp1" WebSite="DefaultWebSite" Directory="WEBAPP1DIR">
      <iis:WebApplication Id="WebApp1IISApplication" Name="webapp1" />
    </iis:WebVirtualDir>
  </Component>

  <Component Id="IIS_WebApp2" Guid="some-guid-2" Directory="wwwrootdir" KeyPath="yes">
    <iis:WebVirtualDir Id="WebApp2VirtualDir" Alias="webapp2" WebSite="DefaultWebSite" Directory="WEBAPP2DIR">
      <iis:WebApplication Id="WebApp2IISApplication" Name="webapp2" />
    </iis:WebVirtualDir>
  </Component>

  <Component Id="IIS_WebApp3" Guid="some-guid-3" Directory="wwwrootdir" KeyPath="yes">
    <iis:WebVirtualDir Id="WebApp3VirtualDir" Alias="webapp3" WebSite="DefaultWebSite" Directory="WEBAPP3DIR">
      <iis:WebApplication Id="WebApp3IISApplication" Name="webapp3" />
    </iis:WebVirtualDir>
  </Component>

</ComponentGroup>

<ComponentGroup Id="IIS_Feature2">
  <Component Id="IIS_WebApp4" Guid="some-guid-4" Directory="wwwrootcustom" KeyPath="yes">
    <iis:WebSite Id="WebApp4Site" Description="Web App 4 Site" Directory="wwwrootcustom" AutoStart="yes">
      <iis:WebVirtualDir Id="WebApp4VirtualDir" Alias="webapp4" Directory="WEBAPP4DIR">
        <iis:WebApplication Id="WebApp4IISApplication" Name="webapp4" />
      </iis:WebVirtualDir>
      <iis:WebAddress Id="WebApp4SiteAddr" Secure="yes" Port="443"/>
    </iis:WebSite>
  </Component>
</ComponentGroup>

我是新来的wix，我猜我的产品有问题。wxs或者有一些我不理解的地方。想法

此问题是在我的安装程序的早期开发过程中发现的。随着更多的开发工作的完成和其他问题的解决，我不再看到这种行为

我从来没有真正弄清楚到底发生了什么，但我注意到，在测试期间，如果安装程序出现一个或多个错误，某些（看似无关的）组件将在卸载过程中留下
