If you put the required DLLs in the same directory as your application they
should be found first (and only) or you can specify the DLLDirectory when
you design your application - setting it to '.\dir' should cause it to try
app\dir (app being your application directory) (I must check just setting
'.' but should work).
The dlls are pretty-well backward compatible - I have successfully used the
1.70 with an app that had 1.50.
