DB2 Connect connection with IE 11

[SRP]

I am first timer.  
I have this code to connect to an IBM mainframe via DB2 Connect. It worked with UFT 11.53  and EI 10, I tested with IE 11 and it failed at objConnection.Open strCon. I upgraded to UFT12 same problem. "[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified"

Set objConnection = CreateObject("ADODB.Connection")
Set objRecordset = CreateObject("ADODB.Recordset")

Dim strCon, SQLStr

strCon = "driver={IBM DB2 ODBC DRIVER - DB2};Database=TestDB2;hostname=DB2CONNSRV1;port=50000;protocol=TCPIP; uid=" & signonuser & "; pwd=" & signonpass

objConnection.Open strCon

Code:

Set cmd = Server.CreateObject("ADODB.Command")
cmd.ActiveConnection = ConnVar
cmd.CommandType = adCmdStoredProc
cmd.CommandText = "Test"
cmd.Parameters.Append(cmd.CreateParameter("@my_date", adVarChar, adParamInput,10))
cmd.Parameters("@my_date") = "10/12/2012"

Set rsResults = Server.CreateObject("ADODB.Recordset")
rsResults.CursorLocation = adUseClient
rsResults.Open cmd,,adOpenForwardOnly,adLockBatchOptimistic

Using CursorLocation = adUseClient means you can navigate the rsResults RecordSet using MoveNext, MoveFirst etc.
