wix - 托管 Bootstrap 应用程序 "Failed to resolve source for file"

Question

在我开始创建自己的自定义托管 Bootstrap 应用程序之前，我使用下面的现有片段没有任何问题，即如果找不到本地文件，它将从互联网下载 .msi。现在，当我尝试执行 MBA 时，我在日志文件中收到以下错误。

[环境]
WiX 3.7、Visual Studio 2012、x64

[Bundle.wxs]

<PackageGroupRef Id="ReportViewer"/>

[片段.wxs]

<PackageGroup Id="ReportViewer">
  <MsiPackage DisplayName="Microsoft Report Viewer 2012 Runtime"
              Cache="no" Compressed="no" ForcePerMachine="yes" Permanent="yes" Vital="yes"
              SourceFile="C:\Program Files (x86)\Microsoft SDKs\Windows\v8.0A\Bootstrapper\Packages\ReportViewer\ReportViewer.msi"
              DownloadUrl="http://go.microsoft.com/fwlink/?LinkID=217022"
              InstallCondition="(VersionNT >= v6.0 OR VersionNT64 >= v6.0)"/>
</PackageGroup>

当本地不存在包时，Burn 引擎会要求您的 Bootstrap 应用程序处理 ResolveSource 调用。如 this other Stack Overflow answer 中所述，您应该为 ResolveSource 事件添加自己的事件处理程序。您可以简单地指示 Burn 为您下载软件包:

this.Bootstrapper.ResolveSource += OnResolveSource;

...

private void OnResolveSource(object sender, ResolveSourceEventArgs e)
    if (!File.Exists(e.LocalSource) && !string.IsNullOrEmpty(e.DownloadSource))
        e.Result = Result.Download;
}
