32-bit Versus 64-Bit Architecture
WinSQL is available for both 32-bit as well as 64-bit architecture. There are three types of ODBC drivers:
132-bit
264-bit
3 32-/64-bit
Depending upon the type of ODBC driver, you must use the appropriate architecture for WinSQL as well. If not, the following error will occur if you try to use a 32-bit driver with WinSQL64.
The specified DSN contains an architecture mismatch between the Driver and Application
