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
