While designed for IRIS, these drivers are often used as the modern successor, though you should verify specific compatibility for older Caché versions.
You don't always need a separate download. The driver is often already on your machine or hidden within the main installer: intersystems cache odbc driver download
InterSystems previously maintained a public FTP at ftp://ftp.intersystems.com/pub/cache/odbc/ . While many users report this is now deprecated or restricted, some specific legacy versions may still be accessible via File Explorer if you have the direct link. 2.

InterSystems Caché ODBC Driver: Download and Setup Guide The InterSystems Caché ODBC driver is a critical bridge for applications—ranging from Power BI to custom Python scripts—that need to communicate with a Caché database. Whether you are maintaining a legacy system or integrating high-performance data into a modern dashboard, finding and installing the correct driver is the first hurdle. 1. Where to Download the Driver While many users report this is now deprecated
If you have the full Caché installer but don't want the database engine, run the setup and choose a "Custom" or "Client Only" installation. This allows you to select just the ODBC components without the full server footprint. 3. Key Compatibility Specs ODBC Compliance: The drivers are compliant with ODBC 3.5 .
For those using the Community Edition or looking for modern drivers that are often backward compatible, the iris-driver-distribution repository is the modern hub.
Generally, IRIS drivers are backward compatible with Caché, but it is a "best effort" scenario. If you are on Caché 2018.1, sticking to the 2018.x drivers is the safest bet for production environments. 4. Configuring the Data Source (DSN)
