How to switch between ODBC drivers in an environment with multiple versions installed

InterSystems FAQ rubric

If multiple InterSystems products are installed on the same system, the latest version of the InterSystems ODBC driver among the installed products will remain registered in the driver manager.

You can change to any driver by changing the registry entry below.

 Please note that running RegFiles.bat does not change the ODBC driver.

The registry entry is as follows.

HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBCINST.INI\InterSystems ODBC35 key Driver
HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBCINST.INI\InterSystems ODBC35 key Setup

The above entry records the path to the driver currently in use.

Change these to the path where the driver you want to switch to exists.
