Applications based on IBDAC require client software only (the gds32.dll or fbclient.dll libraries for InterBase or Firebird correspondingly). IBDAC dynamically loads the client library available on user systems. By default, IBDAC searches client libraries in directories specified in the PATH environment variable. The TIBCConnection.ClientLibrary property is used to specify the path to the client library. Starting with Delphi XE2 it is possible to develop 64-bit applications. To develop 64-bit applications, you should use 64-bit client libraries. For more information, please refer to the "Deployment" and "Database Specific Aspects of 64-bit Development" articles.
