2.06 Driver Portable — Lotus Notessql
If the installer does not do so automatically, manually add your Notes installation folder to the Windows System Environment Variables to ensure the driver can locate required dependencies like nlsxbe.dll . Step 3: Open ODBC Data Source Administrator
The driver cannot find the core Lotus Notes client files or the notes.ini file.
| Error Message | Likely Cause | Potential Solution | | :--- | :--- | :--- | | | The NotesSQL driver version is incompatible with the installed Notes or Domino version. | You need a driver version that matches your Notes client version. For example, using the older NotesSQL 2.06 with a modern HCL Notes 10 client will cause this error. | | "The setup routines for the Lotus Notes SQL Driver (*.nsf) ODBC driver could not be loaded due to system error code 126." | The driver cannot find the necessary Notes client DLLs, usually because the notes.ini file is not in the expected location or the Notes client install is damaged. | Ensure the notes.ini file is in the standard \Lotus\Notes directory. If using a newer Notes client (e.g., v10) with an older driver (e.g., v9), a complex registry hack may be required to trick the driver into working. | | Driver not capable error (23370) | The driver is unable to perform the requested operation. This can be due to an incorrect password in the authentication list or trying to perform an unsupported operation on a particular data type or database structure. | Verify the password stored for the user ID in the NotesSQL Authentication List Manager. Check your SQL query for any unsupported features. | | Driver does not appear in the list of ODBC drivers. | You are likely using the 64-bit ODBC Administrator tool on a 64-bit Windows system, but the NotesSQL driver is 32-bit. | You must use the 32-bit ODBC Administrator ( C:\Windows\SysWOW64\odbcad32.exe ) to configure a System DSN for a 32-bit driver. | lotus notessql 2.06 driver
For context, the Lotus NotesSQL 2.06 driver was succeeded by:
A built-in REST API available in modern Domino versions that exposes views, documents, and attachments as JSON data over HTTP/HTTPS. If the installer does not do so automatically,

: Once the DSN is created, you can use standard SQL commands (e.g., SELECT * FROM TableName ) to query Notes forms as if they were relational tables. Application Integration
