To access a Btrieve database, you must be using the appropriate client software for the version of the Btrieve database to which you are connecting:

Database Versions Client Names
Pervasive.SQL 8.5 Pervasive.SQL 8.5 client software
Pervasive.SQL 2000 Pervasive.SQL 2000 client software
Pervasive.SQL 7.0 Pervasive.SQL 7.0 client software
Btrieve 6.15 for Windows 9x Btrieve Developer’s Kit orBtrieve WorkStation Client Engine
Btrieve 6.15 for Windows NT Btrieve Developer’s Kit, Btrieve WorkStation Client Engine, or Btrieve Client/Server Database Engine
Note: The Btrieve driver may experience problems if the Btrieve Microkernel Engine’s communication buffer size is smaller than that of the Btrieve driver’s Array Size option. You can increase the communication buffer size with the Pervasive Software Setup Utility, or you can decrease the value of Array Size option through the ODBC Btrieve Driver setup dialog box or through the ArraySize connection string attribute.

Before you attempt to access Btrieve files, you must incorporate existing Btrieve files into a Scalable SQL database. See Managing Databases for information about Scalable SQL databases.
