RavenDB UseEmbeddedHttpServer = true "拒绝访问"错误

我试图连接到我的MVC4应用程序内的嵌入式RavenDB数据库:

NonAdminHttp.EnsureCanListenToWhenInNonAdminContext(8080);
documentStore = new EmbeddableDocumentStore
{
       ConnectionStringName = ConnectionStringName,
       UseEmbeddedHttpServer = true
};
documentStore.Initialize();

如果我删除UseEmbeddedHttpServer = true选项，它的工作，我可以正常保存和从数据库读取!但是，如果指定它通过管理工作室(localhost:8080)访问，我会在documentStore.Initialize()中得到Access Denied错误!

这是完整的堆栈:

我以管理员身份运行IIS 7.5和VS2012，并在数据库文件夹中添加了"每个人完全控制"。

我能试什么?
