  1. The files are installed currently during the MSI installation and are located here:

    C:\Program Files\iQuate\iQSonar ScanEngine 4.0\bin\Protocols\Drivers

  2. Stop Scan engine

  3. Copy IBM.Data.DB2.dll and IBM.Data.Informix.dll from there above folders to C:\Program Files\iQuate\iQSonar ScanEngine 4.0\bin

  4.  Restart Scan Engine
