CrystalDecisions.Web.CrystalReportViewer is not defined

I need some help as follows (desperate)

I have a web application in ASP.NET 4.5.1 using Visual Studio 2013 using the Crystal Reports msi 64 bit version 13

My web.config has all the crystal report assemblies.

In my code for using Crystal reports I have the following

Imports CrystalDecisions.Shared

Imports CrystalDecisions.CrystalReports.Engine

Private Sub setReportParameters(ByVal crviewer As CrystalDecisions.Web.CrystalReportViewer)

        Dim paramFields As ParameterFields = New ParameterFields

        Dim pfStartDate As ParameterField = New ParameterField

        Dim pfEndDate As ParameterField = New ParameterField

        Dim pfCreator As ParameterField = New ParameterField

        pfStartDate.ParameterFieldName = "DateStart"

        pfEndDate.ParameterFieldName = "DateEnd"

        creator = User.Identity.Name

        Dim dcStartDate As ParameterDiscreteValue = New ParameterDiscreteValue

        Dim dcEndDate As ParameterDiscreteValue = New ParameterDiscreteValue

        dcStartDate.Value = DateTime.Parse(ddatestart.ToShortDateString())

        dcEndDate.Value = DateTime.Parse(ddateend.ToShortDateString())

        pfStartDate.CurrentValues.Add(dcStartDate)

        pfEndDate.CurrentValues.Add(dcEndDate)

        paramFields.Add(pfStartDate)

        paramFields.Add(pfEndDate)

        crviewer.ParameterFieldInfo = paramFields

    End Sub
