Database Connection fails on some computers

Question

Hi.
We've got some problems with .net application and CR viewer.
We use Visual Studio 2005 and CR XI
Connection is established with the same parameters as the application is connecting with the database:
Private Sub ConfigureCrystalReports()
        Dim crConnectionInfo As ConnectionInfo
        Dim crDatabase As Database
        Dim crTables As Tables, crTable As Table
        Dim crLogOnInfo As TableLogOnInfo
        Dim crSections As Sections, crSection As Section
        Dim crReportObjects As ReportObjects, crReportObject As ReportObject
        Dim crSubreportObject As SubreportObject, crSubreport As ReportDocument
        Using cnn1 As New SqlClient.SqlConnection(ConString)
            crConnectionInfo = New ConnectionInfo
            With crConnectionInfo
                .ServerName = cnn1.DataSource
                .DatabaseName = cnn1.Database
                .UserID = "juhi"
                .Password = "********"
            End With
        End Using
        crDatabase = crreport.Database
        crTables = crDatabase.Tables
        For Each crTable In crTables
            crLogOnInfo = crTable.LogOnInfo
            crLogOnInfo.ConnectionInfo = crConnectionInfo
            crTable.ApplyLogOnInfo(crLogOnInfo)
        Next
        crSections = crreport.ReportDefinition.Sections
        For Each crSection In crSections
            crReportObjects = crSection.ReportObjects
            For Each crReportObject In crReportObjects
                If crReportObject.Kind = ReportObjectKind.SubreportObject Then
                    crSubreportObject = CType(crReportObject, SubreportObject)
                    crSubreport = crSubreportObject.OpenSubreport(crSubreportObject.SubreportName)
                    crDatabase = crSubreport.Database
                    crTables = crDatabase.Tables
                    For Each crTable In crTables
                        crLogOnInfo = crTable.LogOnInfo
                        crLogOnInfo.ConnectionInfo = crConnectionInfo
                        crTable.ApplyLogOnInfo(crLogOnInfo)
                    Next
                End If
            Next
        Next
        CrystalReportViewer1.ReportSource = crreport
    End Sub
On the Clients we have installed CRRedist2005_x86.msi
On some Clients it works perfectly ... on others there is no connection established and after minutes (felt like hours) a login msgbox appears ... with all logon info but the password. But even typing in the correct pw will not establish the connection.

Answer 1

OK. here is your issue:
1) You are using CR XI release 1 Professional to develop an .NET app
2) You are using CR XI release 1 in .NET 2005
CR XI release 1 Professional is not licensed for development and using it as such is breaking the license agreement. As a matter of fact, CR XI Pro does not even install the CR assemblies for .NET(!). The only way you were able to develop is that you downloaded the runtime files as a separate msm download and installed that on the dev computer - not supported - against licenses.
The most likely reason your keycode will not work with CR XI release 1 is that you are now installing the Developer version and you only have the Pro version keycode.
For you to proceed, you will have to uninstall CR XI Pro release 1. Uninstall and CR XI release 2. Clean up your registry. Obtain a valid install of CR XI release 2 Developer. Install that. Update your CR assembly references in .NET. The use the correct runtime for CR XI R2 to distribute your application.
