I don't know what the LIB directory you are referring to is, but if
you have default Delphi settings, bpl and dcp files go into
$(DELPHI)\Projects\Bpl, which is part of the system path (the system's
not just Delphi). This is paramount to be able to compile a design
time package, since it looks for the relevant run time package using
system search order.

Putting the files in the system32 dir usually works because it's
always part of the system search path (otherwise you'd be experiencing
problems well before being able to run Delphi! :-)).

So it looks like
a) your $(DELPHI)\Projects\Bpl folder isn't part of the system path, OR
b) bpl and dcp files aren't put there, OR
c) you aren't compiling the packages in the correct order (IBO comes
with a bpg file with all packages: click on the first one in the
Project Manager with the right mouse button and select "Compile all
from here", the install all the *DT files).

In cases a) and b) you have been messing with the settings, in case
c) you didn't pay attention to the readme. Sorry, your fault. :-)

Let me know if you need additional info to sort it out.

Ciao
