Under most circumstances, modification of data source entries and driver values is not required. In some instances, such as workaround strings to data sources, a registry string modification is required. The registry in 64-bit versions of Windows is divided into 32-bit and 64-bit keys. The default 64-bit version of Registry Editor (regedt32.exe) that is included with 64-bit versions of Windows displays both 64-bit keys and 32-bit keys. It may be used to make modifications to the 32-bit registry key changes required by ECDA.
The 32-bit version of Registry Editor may also be used to change the 32-bit keys required by ECDA. The 32-bit Registry Editor version named regedit32.exe, is located at:
%systemroot%\SysWOW64
To use the 32-bit Registry Editor
Click Start on your desktop.
Click Run.
In the Open box, enter:
%systemroot%\SysWOW64\regedit
Click OK.
The 32-bit registry values used by ECDA are located under the 32-bit programs registry key in the directory: HKEY_LOCAL_MACHINE\Software\ODBC.
The 64-bit Registry Editor displays the 32-bit registry values used by ECDA in the following directory: HKEY_LOCAL_MACHINE\Software\WOW6432Node.
