Hello Experts ,
How I can determine that which ODBC I need to use for creating system DSN:

Why I am asking this because I read that I need system DSN with BI server driver for Direct Database Request connection. However BI Server Driver is listed only under 64 bit.
When I tried to connect with that getting below error:
the setup routine for oracle bi server odbc driver could not be loaded due to system error code 1114: A dynamic link library initialization routine failed

Thanks
