在IIS中向Wix注册ASP.NET站点

我正在尝试在IIS Express 8中注册一个网站。（安装程序也会复制整个站点。）安装程序不会完成，但会执行回滚操作。我尝试了许多不同的方法，但现在我使用以下代码：

    <DirectoryRef Id="INSTALLFOLDER">
  <Directory Id="dir9D67924259071A1E6E852735371F1592" Name="MyWebsiteRoot">
    <Component Id="IISConfiguration" Guid="DAF91C85-A210-479A-B47C-163F61D6CBB1" KeyPath="yes">
      <iis:WebAppPool Id="WebAppPoolId" Name="MyWebSiteAppPool" ManagedPipelineMode="Integrated" Identity="applicationPoolIdentity" ManagedRuntimeVersion="v4.0" />
      <iis:WebSite Id="WebSiteId" Description="MyWebSite" AutoStart="yes" StartOnInstall="yes" Directory="dir9D67924259071A1E6E852735371F1592" >
        <iis:WebAddress Id="WebAddressId" IP="localhost" Port="80" />
        <iis:WebVirtualDir Id="WebVirtualDirId" Alias="/" Directory="dir9D67924259071A1E6E852735371F1592">
          <iis:WebApplication Id="WebApplicationId" Name="My Web Site" WebAppPool="WebAppPoolId" />
        </iis:WebVirtualDir>
      </iis:WebSite>
    </Component>
    ...

我试着修复IIS，也试着只安装一个WebAppPool，但这也会回滚

更新

IISExpress似乎有问题，因为我在安装IIS时没有问题。我会看看我是否能解决这个问题
