Given the age and security risks of running NotesSQL on modern OS, consider these alternatives if you are planning a migration:
| Solution | Approach | Best for | |----------|----------|----------| | HCL Domino REST API (Domino 14+) | RESTful JSON over HTTPS | New development, cloud integration | | NotesSQL 3.02 (unofficial patch) | Community-modified version for Windows 10 | Short-term bridging | | Export to CSV/XML via LotusScript | Scheduled agent writes relational data | One-way reporting | | Third-party ODBC drivers (e.g., Easysoft, CDATA) | Commercial drivers with 64-bit support | Production environments needing modern SQL access |
Recommendation: If you are still dependent on Lotus NotesSQL 2.06 in 2026, plan a migration to HCL Nomad or Domino Volt for API-based access.
The Lotus NotesSQL 2.06 driver (often stylized as NotesSQL) is an ODBC (Open Database Connectivity) driver for Lotus Notes/Domino. It allows external applications—such as Microsoft Excel, Microsoft Access, Crystal Reports, or Visual Basic programs—to access data stored in Lotus Notes databases (.nsf files) using standard SQL commands.
For legacy system administrators and data archivists, version 2.06 represents one of the most stable releases for connecting older Windows systems to Notes data without requiring the full Notes Client programming environment.
The Lotus NotesSQL driver is an ODBC driver that allows external applications—such as Microsoft Access, Excel, Power BI (older versions), Crystal Reports, or custom SQL queries—to read from and write to Lotus Notes databases using standard SQL syntax. It translates SQL queries into Notes Formula Language or LotusScript operations behind the scenes.

Title: How to Download the Lotus NotesSQL 2.06 Driver (ODBC for Lotus Notes)
Introduction
The Lotus NotesSQL driver (version 2.06) is an ODBC-compliant driver that allows external applications—such as reporting tools, ETL platforms, or custom scripts—to read and write data to Lotus Notes databases (.NSF files) via standard SQL queries. Version 2.06 is one of the later releases from IBM (now HCL) and is often required for legacy system integrations.

Security & Support Warning
Using obsolete software like NotesSQL 2.06 on a network-connected system may introduce security risks. Isolate such systems, avoid exposing them to the internet, and consider migrating off the driver if possible.
The Lotus NotesSQL 2.06 driver is a legacy ODBC driver used to access IBM Lotus Notes/Domino data using standard SQL. This specific version is extremely old, dating back to roughly 2001, and has largely been replaced by newer versions like 8.0 or 8.5. Availability and Download Status
Official Support: IBM and HCL (the current owner of Lotus software) no longer provide direct public download links for version 2.06. Most support documentation now points toward newer releases.
Archive Sources: A historic download link was once hosted at www-1.ibm.com, where it was listed as driver 21284 with a file size of approximately 1911k.
Modern Alternatives: For current needs, version 8.0 is more widely available on software archive sites like Software Informer. Key Technical Considerations ODBC driver for Lotus Notes - Tek-Tips
The Lotus NotesSQL 2.06 driver remains a critical piece of legacy middleware for organizations needing to bridge the gap between IBM Lotus Notes/Domino databases and modern relational database management systems. Whether you are performing a one-time data migration or maintaining a long-standing reporting link via Excel or Crystal Reports, finding and installing this specific driver version requires a clear understanding of its compatibility and configuration. Understanding the Lotus NotesSQL 2.06 Driver
The NotesSQL driver is an ODBC (Open Database Connectivity) interface that allows applications to read and write data to Lotus Notes .NSF files using standard SQL queries. Version 2.06 was a milestone release, widely recognized for its stability on 32-bit Windows environments and its ability to communicate with Domino servers ranging from version 6 to early version 8.
Unlike native LotusScript or Java APIs, the NotesSQL driver abstracts the complex hierarchical structure of a Notes database into a flat relational format. This allows non-Notes developers to interact with document-based data using familiar SELECT, INSERT, and UPDATE statements. Where to Download Lotus NotesSQL 2.06
Since IBM transitioned its collaboration software portfolio to HCL Technologies, finding legacy drivers can be challenging.
HCL Software Portal: The primary source for all legacy Lotus software. If your organization has an active entitlement, you can find the driver under the "Notes/Domino" downloads section. lotus notessql 2.06 driver download
Archive and Legacy Repositories: Many IT departments maintain internal repositories for version 2.06 because it is often the "Goldilocks" version for Windows XP and Windows 7 legacy systems.
Third-Party Drivers: If the original IBM installer is unavailable, some developers turn to 3rd-party ODBC bridges, though these often require additional licensing. Key Features and Compatibility
Before initiating a download, ensure your environment meets the specific requirements for version 2.06:
Operating Systems: Optimized for Windows 2000, XP, and Server 2003. It can run on Windows 7/10 (32-bit) in compatibility mode.
Architecture: This is a 32-bit driver. Even on a 64-bit OS, it must be configured using the 32-bit ODBC Administrator (C:\Windows\SysWOW64\odbcad32.exe).
Notes Client Requirement: A local Lotus Notes client or Domino server must be installed on the same machine as the driver to provide the necessary core DLLs. Installation and Setup Guide Follow these steps to ensure a successful deployment:
Prerequisites: Install the Lotus Notes Client. Ensure the Notes program directory (where notes.exe resides) is added to your Windows System PATH.
Execution: Run the setup.exe from the NotesSQL 2.06 package. Follow the prompts to register the driver in the Windows Registry. DSN Configuration: Open the 32-bit ODBC Data Source Administrator. Select the "System DSN" tab and click "Add." Choose "Lotus NotesSQL Driver (*.nsf)."
Provide a Data Source Name, the path to your Notes ID file, and the target database path.
Authentication: The driver will prompt for your Notes ID password when the connection is initialized by the calling application. Common Troubleshooting Tips
"Driver Not Found" Errors: This usually happens when trying to use a 64-bit application (like 64-bit Excel) to call the 32-bit driver. Use the 32-bit version of your reporting software.
Pathing Issues: If the driver cannot find nnotes.dll, double-check your Windows Environment Variables. The driver relies entirely on the Notes Client's binaries. Given the age and security risks of running
Authentication Failures: Ensure the Notes ID being used has "Manager" or "Designer" access to the NSF if you intend to perform write operations; "Reader" access is sufficient for basic queries. The Shift to Modern Alternatives
While the Lotus NotesSQL 2.06 driver is reliable for legacy tasks, modern organizations are increasingly moving toward REST APIs or the HCL Domino Access Services (DAS). If your project involves high-volume data or cloud integration, consider whether an ODBC bridge is the most efficient path forward or if a modernized API approach would better serve your infrastructure.
