Because the BDE is no longer bundled with the OS or the standard RAD Studio runtime, developers must ensure their installation scripts include the necessary merge modules or a dedicated BDE installer. This adds a layer of complexity to the deployment pipeline, as developers must ensure compatibility with various Windows versions, particularly regarding the transition from 32-bit to 64-bit architectures. RAD Studio 10.2 Tokyo supports 64-bit Windows development, and the BDE Installer includes support for 64-bit BDE drivers, which is a critical feature for modernizing legacy application performance.
