ODBC: Another 32/64bit MS undocumented "feature"

There are two different ODBC Administrator runtimes on a 64-bit machine. 

The first ODBC Manager is used to manage 64-bit data sources, while the second is used to manage 32-bit data sources. 

If you are running a 32-bit Operating System, you will have only 32 bit drivers installed. If you are using a 64 bit machine, the default ODBC Manager will be for 64-bit data sources. 

 If you have a 64bit OS and are trying to access a DSN in your 32bit application and receive the error check to see if you have a DSN configured for the architecture of your application ( 32-bit / 64-bit ).

“ERROR [IM014] [Microsoft][ODBC Driver Manager] The specified DSN contains an architecture mismatch between the Driver and Application”
