The specified DSN contains an architecture mismatch between the Driver and Application.

I have installed oracle 11 g release 2 64 bit on Windows 7 OS but when I run c:\windows\syswow64\odbcad32.exe , I don't see the oracle entry in here. Can you please tell me how to add oracle entry here ? I see an entry if I run E:\Windows\System32\odbcad32.exe. The reason I am running from syswow64 is the informatica powercenter designer throws an error "The specified DSN contains an architecture mismatch between the Driver and Application." and the solution is to add entry in here.
