For Borland projects use FTD2XX.DLL from the latest release, but create a LIB file for use with C++ Builder. Borland supplies a utility with C++ Builder called IMPLIB which can be used to create a LIB file from a DLL.
IMPLIB can be run using the following command:
implib ftd2xx.lib ftd2xx.dll
Then FTD2XX.LIB can be linked with the application.
