iis8.5 Sunrise.Web.Upload.HttpUploadModule 异常

Question

最近换成了win2012+IIS8.5服务器，原来的一个VS的老项目发布后其它页面都没问题，就是调用了一个上传文件的Sunrise.Web.Upload.DLL控件出错，附件不管上传没上传 一点保存就出错，如下：
[NullReferenceException: 未将对象引用设置到对象的实例。]
Sunrise.Web.Upload.HttpUploadModule.Application_BeginRequest(Object sender, EventArgs e) +5982
System.Web.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +80
System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +171
