Well, call them at their Customer Support number which happens to be in the
UK (checking my files....yep, here it is...number coming up) at:
0734-321150

This is the Run Time module for the programs.  It should be in the path.  I
believe that you can deliver it with your apps.
The other PC did ti have this file in the path so it would not run.  The
DLL contains calls and functions necessary to make the program run.

Are you clicking on the DLL file?  No, no, do not do that.  Just copy it
somewhere in the path like in Windows or system directory of windows so
your program can use it.

(The only file BC450RTL.DLL that I can find in my PC is

\WINDOWS\.

Exactly!  It is a run time module.  Like vbx100.dll, vbx200.dll, vbx300.dll
etc.....
With RSXNTDJ for example there is the RSXNT.DLL, and so on and so forth to
make the story simple.

Yes, you can.  Just deliver it with the app!  Also, did you know that most
of the exe's you see in your OS, like windows, depend on dll's like that to
run.  Just get used to it.  The point of these files is to save space by
letting apps call certain functions from them so that you do not have to
reinvent the wheel every time you work on an app where certain function and
system calls can be shared.

This defeats the purpose of the Dynamic Link Library (DLL) -- get it :) --
but I think that you can do that if you insist.  One way is to link the
objects that make up the dll with the app.  Then do that with EVERY app you
create.  I believe that you have to give the dll's a fresh look.  There is
more to it and there is lots of literature on the dll's and how to utilize
them fully.  However, as long as the dll in the path you should be fine. 
And just deliver the run time dll with your app.
