Access error message. What does this mean?

I've been having one roadblock after another after another (in case you look
through the other posts) trying to access an Access database from a Delphi
.dll using a TADOConnection. When I call Open() I am getting errors trying
to connect to ANY Access database but not any other kind (such as SQL
Server).

After much hacking around I finally got Delphi to generate an error message
with more informative text to it by setting my connection string to point to
a *.udl file instead of setting the connection string to an actual
connection string containing the database environment particulars.

Error Message: Non-NULL controlling IUnknown was specified, and either the
requested interface was not IUnknown, or the provider does not support COM
aggregation.

Does anyone have a clue what the heck this is implying (exactly. not
supposed conjecture)?

I am fearful that Access cannot be accessed using ADO imported by a .dll
now.... this is what I am sensing from the error message, but this makes no
sense to me at all because why would Microsoft make such a piece of s***
database and expect the entire world to use it?
