This topic contains the environment changes made by the LiteDAC installer. If you are having problems using LiteDAC or compiling LiteDAC-based products, check this list to make sure your system is properly configured.

Compiled versions of LiteDAC are installed automatically by LiteDAC Installer for all supported IDEs except for Lazarus. Version of LiteDAC with Source Code must be installed manually. Installation of LiteDAC from sources is described in the supplied ReadmeSrc.html file.

Before installing LiteDAC ...

Two versions of LiteDAC cannot be installed in parallel for the same IDE, and, since the Devart Data Access Components products have some shared bpl files, newer versions of LiteDAC may be incompatible with older versions of ODAC, IBDAC, SDAC, MyDAC, PgDAC and UniDAC.

So before installing a new version of LiteDAC, uninstall all previous versions of LiteDAC you may have, and check if your new install is compatible with other Devart Data Access Components products you have installed. For more information please see Using several products in one IDE. If you run into problems or have any compatibility questions, please email [email protected]

Note: You can avoid performing LiteDAC uninstallation manually when upgrading to a new version by directing the LiteDAC installation program to overwrite previous versions. To do this, execute the installation program from the command line with a /force parameter (Start | Run and type litedacXX.exe /force, specifying the full path to the appropriate version of the installation program).

Environment Changes

To compile LiteDAC-based applications, your environment must be configured to have access to the LiteDAC libraries. Environment changes are IDE-dependent.

For all instructions, replace %LiteDAC% with the path to your LiteDAC installation directory


The LiteDAC Installer performs Delphi environment changes automatically for compiled versions of LiteDAC.

The LiteDAC Installer performs C++Builder environment changes automatically for compiled versions of LiteDAC.


The LiteDAC installation program only copies LiteDAC files. You need to install LiteDAC packages to the Lazarus IDE manually. Open %LiteDAC%\Source\Lazarus1\dcllitedac10.lpk (for Trial version %LiteDAC%\Packages\dcllitedac10.lpk) file in Lazarus and press the Install button. After that Lazarus IDE will be rebuilded with LiteDAC packages.

Do not press the the Compile button for the package. Compiling will fail because there are no LiteDAC sources.

To check that your environment has been properly configured, try to compile one of the demo projects included with LiteDAC. The LiteDAC demo projects are located in %LiteDAC%/Demos.


DBMonitor is an easy-to-use tool to provide visual monitoring of your database applications. It is provided as an alternative to Borland SQL Monitor which is also supported by LiteDAC. DBMonitor is intended to hamper application being monitored as little as possible. For more information, visit the DBMonitor page online.
