This is my Exceptio on Run Time

{"Could not load file or assembly 'file:///C:\\Program Files (x86)\\SAP BusinessObjects\\Crystal Reports for .NET Framework 4.0\\Common\\SAP BusinessObjects Enterprise XI 4.0\\win32_x86\\dotnet1\\crdb_adoplus.dll' or one of its dependencies. The system cannot find the file specified.":"file:///C:\\Program Files (x86)\\SAP BusinessObjects\\Crystal Reports for .NET Framework 4.0\\Common\\SAP BusinessObjects Enterprise XI 4.0\\win32_x86\\dotnet1\\crdb_adoplus.dll"}

Is this exception thrown from a client or the dev machine?

If this is from the client, you need to install Crystal Reports.

this from my home laptop and i am using vb.net and i have installed the crystal reports i am getting this exception by generating a dynamic crystal report

no i have downloaded the crystal reports from the SAP website and installed it but i dont know why this exception is occuring
