qpro200.dll is its own little DLL hell

[Dan Kegel]

The VB app I'm trying to bring up (Yardi) installs qpro200.dll.
Amusingly, their setup utility crashes on startup if
you run it again, in that dll's init routine.
Deleting it seems to fix things.  Good old DLL hell.
Partial relay and traceback attached in case anyone's curious.
