Can not able to see 64 bit ODBC driver from SSIS odbc connection

Hi,

I am using SSIS 2014 with the below .net framework version and installed in Windows server 2012 R2 . I have installed my client's odbc drivers (both 32 bit and 64 bit) in my production server and created ODBC system DSNs for 32 bit and 64 bit.

When i open SSIS 2014 and tried to create the odbc connection but i can able to see only the 32 bit system DSN connection ,i can't able to see my 64 bit odbc system dsn connection.

Microsoft Visual Studio 2012 Shell (Integrated)
Version 11.0.50727.1 RTMREL
Microsoft .NET Framework
Version 4.5.51650

SQL Server Integration Services   
Microsoft SQL Server Integration Services Designer
Version 12.0.1524.0
And i installed my client odbc drivers(32,64 bit) and created ODBC system DSNs in my local system and when i open ssis 2014 and i can able to see both the ODBC system DSNS(32,64) connections from SSIS ODBC connection.

I am using below version of .net framework in my local system which was installed in windows 7 and i have SSIS 2012 also installed in my system and i can able to see both ODBC connections using 2012 as well in my local system.

Microsoft Visual Studio 2012 Shell (Integrated)

Microsoft .NET Framework
Version 4.5.50938

Can any one please suggest me why i can not see the ODBC 64 bit system DSN connection from SSIS in my production server ??
