Bde Installer For Rad | Studio- Delphi- C Builder 10.2 Tokyo
The BDE installer writes keys to the Borland root. But 10.2 Tokyo looks for Embarcadero roots. You must merge them.
Open Registry Editor and navigate to:
HKEY_CURRENT_USER\SOFTWARE\Embarcadero\BDS\18.0\Known IDE Packages
Add a string value:
Next, navigate to:
HKEY_CURRENT_USER\SOFTWARE\Embarcadero\BDS\18.0\Library
Add a path to the system PATH environment variable via the IDE (Tools > Options > Environment Variables > System Path): Add C:\Program Files (x86)\Common Files\Borland Shared\BDE
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.

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.
To use the Borland Database Engine (BDE) with RAD Studio 10.2 Tokyo, you must perform a manual installation because the BDE is no longer included in the standard IDE setup. While the engine is deprecated and superseded by technologies like FireDAC, an official external installer remains available for developers maintaining legacy systems. 1. Downloading the BDE Installer for 10.2 Tokyo
Embarcadero provides a dedicated installer specifically for each RAD Studio version. To find the one for 10.2 Tokyo: BDE Installer For RAD Studio- Delphi- C Builder 10.2 Tokyo

Once you have the BDEInstaller.exe (or similar), follow these steps to integrate it with your IDE:
Run the Installer: Execute the downloaded file with administrator privileges.
IDE Recognition: The installer should automatically detect your 10.2 Tokyo installation paths.
Manual Component Registration: If the BDE components (TTable, TQuery, etc.) do not appear in your Tool Palette, you must install the design-time package manually: Open RAD Studio 10.2 Tokyo. Navigate to Component > Install Packages.
Click Add and browse to your binary directory (typically C:\Program Files (x86)\Embarcadero\Studio\19.0\bin).
Select the file dclbde250.bpl (the 250 suffix corresponds to the Tokyo version). 3. Post-Installation Configuration
After installation, you may need to use the BDE Administrator (bdeadmin.exe) to manage aliases and system settings:
Windows 10/11 Compatibility: Run the BDE Administrator as an Administrator to ensure it can save changes to the registry and the IDAPI32.CFG file.
Shared Memory: If you encounter "Insufficient memory" errors, adjust the SHAREDMEMSIZE in the BDE Administrator under Configuration > System > INIT. 4. Why Use the BDE in 2026?
The BDE is officially deprecated and does not support modern features like Unicode or 64-bit architecture. It is strictly used for: The BDE installer writes keys to the Borland root
Installing Component Packages - RAD Studio - Embarcadero DocWiki
Installing the deprecated Borland Database Engine (BDE) in RAD Studio 10.2 Tokyo requires downloading a separate installer from the Embarcadero Registered Users Portal and enabling the design-time components ( dclbde190.bpl
) in the IDE. Due to lack of Unicode support, migrating existing BDE projects to FireDAC is strongly recommended. For more details, visit the Embarcadero DocWiki BDE Support for Delphi 10.4.2 - General Help

In the rapidly evolving landscape of software development, backward compatibility remains both a blessing and a challenge. Embarcadero’s RAD Studio 10.2 Tokyo, released in 2017, represents a modern Integrated Development Environment (IDE) supporting cutting-edge technologies such as FireMonkey, High-DPI displays, and multi-tier database frameworks. However, many enterprises and independent developers still rely on legacy database applications built upon the Borland Database Engine (BDE). Originally introduced in the 1990s with Delphi 1 and C++ Builder 1, the BDE became the standard way to connect Paradox, dBase, Access, and local InterBase databases.
