.net app using crystal reports not working on development server

Question

i have a .net app that was in .net 3.0 and using crystal reports 10.5 we migrated to .net 4.5 and a new development/testing web server using .net 4.5 now the application will not load.

the errors that i receive are:

Server Error in '/' Application.

i have installed the crystal runtime.

i'm not sure what else to try.

thanks

Are the following files in the bin directory of your website/application? crystaldecisions.crystalreports.engine.dll, crystaldecisions.reportsource.dll, crystaldecisions.shared.dll, crystaldecisions.web.dll.

Also, I believe that version of CR is compiled under .NET 2.0 so you may need to enable the legacyV2 runtime. You can do so via the app.config file by adding useLegacyV2RuntimeActivationPolicy="true" to the startup element. Or, you can do it in code by using the RuntimePolicyHelper class. eg.

Imports System.Runtime.InteropServices
Imports System.Runtime.CompilerServices

'instantiate your class

Public Sub New()

    Try
        'runtime support for mixed mode assemblies
        'this is used to load .NET 2.0 assemblies that crystal reports is built against.
        If RuntimePolicyHelper.LegacyV2RuntimeEnabledSuccessfully = True Then

        Else
            If MsgBox("Legacy CLR could not be loaded. Continue?", _
                      vbYesNo + vbExclamation, _
                      "Failed to load legacy runtime.") = vbNo Then
                Application.Exit()
            End If
        End If
    Catch ex As Exception
        ex = New Exception(ex.Message & vbCrLf & ex.StackTrace)
        Throw ex
    End Try

End Sub

Public NotInheritable Class RuntimePolicyHelper
    Private Sub New()
    End Sub
    Public Shared Property LegacyV2RuntimeEnabledSuccessfully() As Boolean
        Get
            Return m_LegacyV2RuntimeEnabledSuccessfully
        End Get
        Private Set(value As Boolean)
            m_LegacyV2RuntimeEnabledSuccessfully = value
        End Set
    End Property

    Private Shared m_LegacyV2RuntimeEnabledSuccessfully As Boolean

    Shared Sub New()
        Try

            Dim clrRuntimeInfo As ICLRRuntimeInfo = _
              DirectCast(RuntimeEnvironment.GetRuntimeInterfaceAsObject(Guid.Empty, _
              GetType(ICLRRuntimeInfo).GUID), ICLRRuntimeInfo)
            Try
                clrRuntimeInfo.BindAsLegacyV2Runtime()
                LegacyV2RuntimeEnabledSuccessfully = True
            Catch generatedExceptionName As COMException
                LegacyV2RuntimeEnabledSuccessfully = False
            End Try

        Catch ex As Exception
            ex = New Exception(ex.Message & vbCrLf & ex.StackTrace)
            Throw ex
        End Try
    End Sub

Please note that I didn't come up with this code - I may have even found it on this site - but I can't find the original contributor. However, it works for me so you may want to give it a try.
