Getting Error

[Mujeeb]

I have one asp.net website application. In this application i used rad-control . now i installed the teleric rad control . But i am getting the following error. Bcz its working fine in production server . I dont know much  more about this application . Now i configured my application in locally for enhancement.  Now my doubt is just installtion is required or whether we want to add any refernce to bin folder or not. If yes tell me. Other wise plz provide some tips to resolve this issue
