Wix管理引导程序

我的bundle.wxs中链接了一些ExecPackages。我有一个用于安装.Net Framework 4.0的PackageGroup部分。这已作为PackageGroupRef挂在链的开头。 当我双击引导程序时，会弹出一个安装.Net Fwk的.Net framework安装窗口。在安装.Net之后，我希望引导程序能够显示托管UI并继续实际的安装活动。 但是，问题是它只是在.Net framework安装后停止。我必须再次执行引导程序，UI才会弹出并恢复安装。bundle.wxs内容如下所示：

好吧，至少从简化的捆绑代码开始。如果测试机器已经安装了任何版本的.NET，请添加。编辑上面的帖子以添加Bundle.wxs内容。
