Similarly, the 64-bit ODBC driver that is installed with iSeries Access for Windows on a 64-bit Windows PC is \windows\system32\cwbodbc.dll and the 32-bit driver is \windows\SysWOW64\cwbodbc.dll. This does not apply just to ODBC related files.
Note: All available information indicates that all 64-bit files are stored in System32 and all 32-bit files are stored in SysWOW64. The \windows\SysWOW64\odbcad32.exe is the 32-bit ODBC Administrator. The \windows\system32\odbcad32.exe is really the 64-bit ODBC Administrator.
Some things in 64-bit Windows are the opposite of what you would expect. One would think that the 32-bit system files would go in the System32 directory and the 64-bit system files would go in the SysWOW64 directory. Both versions can be accessed from the iSeries Access for Windows folder.Ħ4-bit Windows has the familiar C:\Windows\System32 directory, and it also has a C:\Windows\SysWOW64 directory that serves a similar function as a repository for system files. Both versions are named odbcad32.exe (there is no odbcad64.exe). Microsoft provides the following versions of the ODBC Administrator: 32-bit and 64-bit. ODBC applications running in 64-bit versions of Windows will automatically use the appropriate ODBC driver, depending on whether the application was compiled as 32-bit or 64-bit. The 64-bit ODBC driver is automatically installed along with the 32-bit ODBC driver when running under a 64-bit version of Microsoft Windows. IBM iSeries Access for Windows provides both a 32-bit and 64-bit ODBC driver.
