Question : How to connect to crystal reports 8.x from vb6 in Windows 7

Hi!  I have a vb6 application which runs crystal reports 8.x reports via the OCX control.  The system ran just fine under Windows XP and MSDE using the following connection string:
        'SQL Server driver - use for MSDE connections
        gstrRptConnectString = _
            "uid=sa;" & _
            "pwd=;" & _
            "driver={SQL Server};" & _
            "server=(local);" & _
            "database=FLDACM;" & _
            "dsn = ''"
When I launch the reports, I set to report OCX''s Connect property to that connection string:
            Me.CRpt1.Connect = gstrRptConnectString
And everything works just fine.

Now I am trying to migrate the application to run under Windows 7 and SQL Express 2005.  I have had to change my main login to a new driver and format, e.g.,
        gstrRptConnectString = _
            "Provider=SQLNCLI.1;Integrated Security=SSPI;" & _
            "Persist Security Info=True;" & _
            "Trusted_Connection=no;" & _
            "Persist Security Info=True;" & _
            "Server=servername\instancename;" & _
            "Initial Catalog=FLDACM;" & _
            "User ID=username;" & _
            "Password=password"
And this works with the ADO in my vb6 applicationn the new Windows 7 / SQL Express 2005 environment.  But when I try to launch the Crystal Reports reports from my application I get the following error:

Error # 20599 - Cannot open SQL Server.

I have tried all these other connection strings, with no success launching crystal reports in the Windows 7 / SQL Express 2005 environment:

    'Setup the crystal reports connection string - works on development machine, not on lenovo
   
    'this uses the same connection as the front end - doesn't work at all
'    gstrRptConnectString = gstrConnectString

    'this uses a system DSN - doesn't work at all
'    gstrRptConnectString = "DSN=FLDACM;" & _
'                           "Uid=sa;" & _
'                           "Pwd=Welcome1"

    'this is the standard sql connection -  doesn't work at all
    gstrRptConnectString = "Server=servername\instancename; " & _
                           "Database=FLDACM; " & _
                           "UID=username; " & _
                           "PWD=password; "

    'This is the SQL Native Client 9.0 - doesn't work at all
     gstrRptConnectString = "Provider=SQLNCLI; " & _
                            "Server=servername\instancename; " & _
                            "Database=FLDACM; " & _
                            "Uid=username; " & _
                            "Pwd=password; "

     gstrRptConnectString = "Data Source=servername\instancename; " & _
                            "Initial Catalog=FLDACM; " & _
                            "User Id=username " & _
                            "Password=password;"
                           
    gstrRptConnectString = "Driver={SQL Native Client}; " & _
                            "Server=servername\instancename; " & _
                            "Database=FLDACM; " & _
                            "Uid=username " & _
                            "Pwd=oasswird; "

I have also verified that all the necessary support DLLs reside in theWindows 7 / SQL Express 2005 environment, so I do not think it is a missing DLL issue.

Is there any connection string format that will work with Crystal Reports 8 and Windows 7 / SQL Express 2005?
