On 64 bit systems the system environment e.g. "program files" folder and the system registry entries exist twice, for 64 bit applications and for 32 bit applications. These two environments are strictly separated so that a configuration done in the first will not be seen in the second one. This also applies to the ODBC subsystem.

There are two ODBC administrators to define data sources for the 64 bit and for the 32 bit environment. If you simply start the "ODBCAD32.EXE" either directly or from a system panel you will always get the 64 bit version and data sources that you define will only be usable from 64 bit applications. This "ODBCAD32.EXE" is located in the "\WINDOWS\SYSTEM32" directory. Microsoft kept the original names in their folders and EXE files so "\WINDOWS\SYSTEM32" really contains 64 bit applications and the "ODBCAD32.EXE" that you find there is a 64 bit version of the administrator.

If you want to configure the 32 bit ODBC subsystem you have to use the "ODBCAD32.EXE" from the "\WINDOWS\SYSWOW64" folder. This is the ODBC administrator that you have to use when you are configuring ODBC data sources for 32 bit applications that run under 64 bit Windows.

Only in the case that you have a 64 bit application you would need a 64 bit PARKWAY product. For this you can contact us via our contact form.
