Hi,

I have no idea how to do this on a client's computer, or make an
installation program to do this on a client's computer:

My main application was written in VB6.0.  It used to use a VJ6.0 ActiveX
dll for Java's BigInteger class.  Of course, there is no longer a MSJVM for
that dll, so I can't use it anymore because it won't work on most clients'
computers.  So I rewrote the dll in VJ#, created the type library, did the
whole thing with making the strong name, etc. to make a COM Callable
Wrapper.

In VB6.0 I just make a reference to the type library of my VJ# dll and I can
use the dll--everything works fine.  It treats the dll like an ordinary
ActiveX dll on my development computer, and my main application can use it
properly.

When I try to install the main program (I usually use Inno Setup to make the
installation program) and the dll onto a client machine and use the dll, I
get the Error 429: unable to create ActiveX component.

Two longshot things I have considered are rewriting BigIntegers from scratch
in VC6.0 (*a lot* of trouble!), and migrating the entire source into VS.net
(the codebase is kind of large though!)

What should I do?
