The Complete Guide to Installing and Configuring BDE for RAD Studio, Delphi, and C++Builder 10.2 Tokyo
The Borland Database Engine (BDE) is one of the most enduring legacy database technologies in the history of Delphi and C++Builder development. Although Embarcadero officially deprecated the BDE years ago, thousands of enterprise applications worldwide still rely on it to connect to dBase, Paradox, and SQL databases.
FireDAC is a universal data access library developed by Embarcadero. It is the modern successor to the BDE, offering high-performance, native access to a wide range of databases. It supports 64-bit and Unicode, which the BDE does not, and is the recommended migration path for all new applications and for modernizing legacy BDE projects.
Once installed, you may need to configure the BDE Administrator, particularly if your application requires specific database aliases.
Embarcadero provides a built-in migration utility called the . This command-line utility scans your source files ( .pas , .cpp , .dfm ) and automatically replaces BDE references with their corresponding FireDAC alternatives (e.g., changing TTable to TFDTable and TQuery to TFDQuery ).

The process requires installing the core BDE runtime engine, the BDE design package to display components in the Tool Palette, and activating the optional SQL Links for database connectivity. However, as the BDE is deprecated, it is not distributed with the main setup. You must download it as a separate component from Embarcadero's Registered User Downloads page.
Ensure the PATH points to the folder containing your .DB or .DBF files. Click > Apply to save changes. Key Considerations and Troubleshooting
Right-click your compiled Delphi/C++Builder application executable and select Run as Administrator . If this fixes it, you need to grant full read/write permissions to the BDE directory ( C:\Program Files (x86)\Common Files\Borland Shared\BDE ) for your standard users. Error: "Cannot load driver" or missing components
When distributing an application compiled in RAD Studio 10.2 Tokyo that uses the BDE, you cannot simply copy your .exe file. The target machine must have the BDE engine installed. To deploy successfully: The Complete Guide to Installing and Configuring BDE
