[AccessD] Save dll to folder

I am into a situation where I need to save a dll to computers that are
already installed.

Does a dll HAVE to be in the system32 directory?  If so, how do you account
for possible different folder names for this location?  What I want to do is
send the dll to the client as part of an upgrade.  Upon needing the dll, the
app could check for its existence and copy it to the proper location.
However, if the folder is not system32, how do I be sure to get the right
fodler name?

If not, how can I point the app to look for the dll elsewhere?  Ideally, I
would simply set the dll in a folder with the app.

Thanks.
