我已经安装了 VS-2012 Express Edition。现在，我正在尝试创建 Silverlight 应用程序。
一开始，我以以下错误结束：
在创建 Silverlight 项目之前，您需要安装最新的 Silverlight Developer 运行时。在以下位置下载 x86 运行时：go.microsoft.com/fwlink/?LinkId=229323
因此，我从上面给定的 URL 下载了 Silverlight Developer 运行时，并尝试再次创建 Silverlight 应用程序。
当我单击“新项目”对话框上的“确定”按钮时，我收到以下错误。
可能是什么原因？有人可以建议解决方案吗？
错误摘要如下：
