Report does not display on server

I added a report to my project, when I run it in Visual Studio it works fine. When I publish and copy files in 

C:\inetpub\wwwroot\project12

aspnet_client

project12

These solutions did not help. What else can I do to fix this?

• Crystal Report Issue with IIS - ( bobj is undefined , Crystal report not displaying )
