Hello!
If you use the package without sources, then you have all *.Dcu, *.Hpp and *.Obj precompiled files which used by compiler. If compiler says, that acAlphaHints.pas can’t be found then be sure that files acAlphaHints.dcu, acAlphaHints.hpp and acAlphaHints.obj are existing in the folder with components.
Compile acntCX11alexandria_r.cbproj firstly and install acntCX11alexandria.cbproj after that.
