Habría que leer detenidamente la licencia, pero en la página pone esto:
The Turbo Explorer editions cannot use 3rd party components or plug-ins. Upgrade to the Professional editions of Delphi, C++Builder or CodeGear RAD Studio to use other VCL custom controls, components and experts, including those from 3rd party vendors.
Dice: "cannot use", no "
cannot install"; No se si eso te aclara algo...
