Before committing, consider the modern alternatives. Embarcadero recommends migrating to:
However, migration costs (man-hours, testing, regression bugs) often outweigh the convenience of the BDE. For a team maintaining a 500,000-line legacy payroll or inventory system, the BDE Installer for RAD Studio- Delphi- C++ Builder 10.2 Tokyo is the pragmatic choice.
