Location

---

ODBC drivers are installed and configured using the registry in Windows. The location of the driver entries is the following registry key:

HKEY_LOCAL_MACHINE\Software\ODBC\ODBCINST.INI\<Driver Name>

In addition, the name of the driver must also be added to the following registry key:

HKEY_LOCAL_MACHINE\Software\ODBC\ODBCINST.INI\ODBC Drivers

The name of the registry value is the name of the ODBC driver, and the data for the registry value is a string with the value "Installed" (without surrounding double quotes). For example, for the DBISAM 4 ODBC Driver, the entire registry key and value would be the following:

Key: HKEY_LOCAL_MACHINE\Software\ODBC\ODBCINST.INI\ODBC Drivers

Value Name: DBISAM 4 ODBC Driver
Value Type: STRING
Value Data: Installed

64-bit Windows

Under 64-bit Windows, the above registry keys/values are for 64-bit drivers only. In order to configure 32-bit drivers on 64-bit Windows, one must use the following registry key instead:

HKEY_LOCAL_MACHINE\Software\Wow6432Node\ODBC\ODBCINST.INI\<Driver Name>

In addition, the name of the driver must also be added to the following registry key:

HKEY_LOCAL_MACHINE\Software\Wow6432Node\ODBC\ODBCINST.INI\ODBC Drivers

The following registry values are defined under the <Driver Name> key in the registry (see above). These registry settings are all required, and should be specified exactly as indicated in order to ensure proper operation.
