获取System.Exception：应用程序在我的应用程序中没有许可

Question

您好我输入网址时收到以下异常

APPLICATION: Not Licensed. 
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

Exception Details: System.Exception: APPLICATION: Not Licensed.

Source Error: 


An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.


Stack Trace: 


[Exception: APPLICATION: Not Licensed.]
   Application.Application_BeginRequest(Object sender, EventArgs e) +112
   System.Web.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +148
   System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +75

这是网址 http://ticketsystem./Home/ConfirmAttendance/34915?vt=635xj1hogLSgWWALEfaKJ3cM3uo%3D

即使ticket或vt参数无效，它们是否应该获得更具体的异常，例如“id invalid or vt code invalid？”

这是什么错误？我以前从未见过它。

请告知。

由于
