The Borland Database Engine (BDE) is a legacy database technology that is no longer included by default in RAD Studio 10.2 Tokyo. Because the BDE is deprecated, Embarcadero provides it as a separate, optional add-on for registered users who must maintain older applications. Key Installation Information
Availability: The BDE installer is an external download for registered users of RAD Studio, Delphi, or C++Builder 10.2 Tokyo.
Official Download: It is typically found in the "My Downloads" section of the Embarcadero Portal.
Specific Version ID: For 10.2 Tokyo, the BDE installer was historically identified as Item 30752 on Embarcadero’s CodeCentral. How to Install BDE Components in the IDE
Simply running the installer places the BDE files on your system, but you must manually enable the components in the RAD Studio 10.2 IDE to see them in the Tool Palette: Run the Installer: Complete the external BDE setup process.
To install the Borland Database Engine (BDE) for RAD Studio 10.2 Tokyo, you must use a separate installer because it is no longer bundled with the IDE by default. The process involves downloading the specific BDE Add-on, running the installer, and manually registering the components within the Tokyo IDE. 1. Download and Basic Installation
The BDE remains deprecated, and for modern development, experts from Embarcadero DocWiki recommend migrating to FireDAC. If you must use it:
Locate the Installer: Registered users can find the "BDE Installer for RAD Studio, Delphi, C++Builder 10.2 Tokyo" in the Embarcadero Registered Users Download Portal.
Run Setup: Double-click the installer to place the BDE core files on your system.
Best Practice: In modern Windows environments with User Account Control (UAC), it is recommended to install the BDE in a root directory (e.g., C:\Borland\BDE) rather than within "Program Files" to avoid permission issues. 2. Registering BDE Components in the Tokyo IDE
Installing the engine does not automatically add the components to your Tool Palette. You must manually install the design-time package: Launch RAD Studio 10.2 Tokyo.
Let’s be honest: Nobody wants to add the BDE to a new project. But if you are supporting a Paradox, dBASE, or legacy InterBase system built 15–20 years ago, migrating the data layer might cost thousands of hours. The BDE Installer allows you to:
Embarcadero no longer actively distributes the BDE on its main website. However, registered users can find it via:
Legacy or Redist folder for BDEInstaller.exe.Caution: Avoid unofficial download sites offering "cracked" or "free" BDE installers. They often contain malware. Stick to the official GetIt or Embarcadero login-gated downloads.
Cause: The IDAPI32.DLL is not registered or a dependency (MSVCRT40.DLL) is missing.
Fix: Copy MSVCRT40.DLL from an old Windows 7 machine (or SysWOW64) into C:\Program Files (x86)\Common Files\Borland Shared\BDE. Regsvr32 it.
RAD Studio 10.2 Tokyo holds a unique position. It is the last version that fully supports the Classic Borland Compiler (BCC32) alongside the newer Clang-enhanced compiler. If you have BDE components (TDatabase, TTable, TQuery) on a form, 10.2 Tokyo is the most stable modern IDE to support them without rewriting your data module.

Crucial Note: By 10.3 Rio, the BDE installer became a purely community-maintained artifact. In 10.2, the official (though hidden) support still exists.
RAD Studio 10.2 Tokyo remains a rock-solid IDE, and the BDE Installer ensures that your decade-old codebase can still be opened, compiled, and debugged. Follow the steps above, stay on 32-bit, and you’ll be back to maintaining that legacy inventory system in no time.
